New Testament Growth in Christ: From Foundation to Fullness

 New Testament Growth in Christ: From Foundation to Fullness

The New Testament presents a vibrant and multifaceted picture of spiritual growth, not as a static event but as a dynamic, lifelong journey for the believer. This journey, with emphasis on a strong foundation, progresses through a transformative process of maturity forged by endurance, ultimately aiming for the profound goal of experiencing the "fullness of God in Christ."

The Foundation: A New Creation

The inception of growth in Christ is marked by a radical spiritual new birth, a foundational shift that defines the Christian experience. It is not merely a moral reformation, but a divine act of creation. The apostle Paul declares this truth in 2 Corinthians 5:17: "Therefore, if anyone is in Christ, he is a new creation. The old has passed away; behold, the new has come." This new creation is initiated by faith in Jesus Christ, where believers are justified and reconciled to God through His sacrifice.

The new birth is often described as being "born a new" or "born of the Spirit," as Jesus explained to Nicodemus in John 3:3-6: "Truly, truly, I say to you, unless one is born a new he cannot see the kingdom of God... That which is born of the flesh is flesh, and that which is born of the Spirit is spirit." This spiritual birth provides the very seed of divine life, establishing the believer's identity in Christ and setting the stage for subsequent development.

The Holy Spirit, promised by Christ, indwells the believer at this foundational stage, serving as a down payment and guarantor of future inheritance (Ephesians 1:13-14). This initial indwelling empowers the believer and acts as an agent of growth and transformation.

Paul writes there are three foundational principles of growth; new birth of the spirit, faith, and love. In Ephesians 3: 16-19 he explains what is essential to growth, praying that God grants the church strength through the spirit in the inner being, Christ dwelling in the heart through faith, and being rooted in love, so to be filled to the fullness of God.

Paul write In Colossians 2:7, "just as receiving Christ Jesus the Lord [through faith], also walk in him, rooted and built up in Him and established in the faith, just as you were taught…” 

We can add hope to faith and love, as faith exists hope, Hebrews 11:1. So now abides faith, hope, and love and the greatest of these is love, 1 Corinthians 13:13. This foundation is necessary, it is the path to becoming a man, putting off childish ways, and it is how we establish our identity in Christ, 1 Corinthians 13:11-12 and Ephesians 4:13-14.  

Have you been taught this? Do you have such a foundation? To be born of the Spirit, rooted and built up and established in faith, and rooted and founded in love. You will need a firm foundation to endure the thorns so to grow up to fullness.

Maturity Through Endurance: The Process of Sanctification

Once established in Christ, the journey of growth moves into a continuous process of sanctification, where the believer is being conformed to the image of Christ. This is not an instantaneous event but a gradual, often trying, transformation and renewing of the mind. It is in this phase that "maturity through endurance" becomes paramount. James states endurance has this intended purpose of maturing us.

"My brother when you encounter various trials know that the proving of your faith works out endurance, now, having endurance you have its intended purpose, so that you exist mature and whole, lacking in nothing,” James 1:1-4. 

The New Testament consistently emphasizes the necessity of perseverance through trials and difficulties. Romans 5:3-4 articulates this truth: "More than that, we rejoice in our sufferings, knowing that suffering produces endurance, and endurance produces character, and character produces hope." Here, suffering is not like the world sees it, a detour or just something we bear through, but the trial is a divinely appointed pathway to spiritual maturity. It refines faith, deepens reliance on God, and purifies character,. The trial is refining and proving us.

Furthermore, this growth is fostered through active engagement with God’s word in which the regenerative power of the Holy Spirit works. The study and application of God's Word are crucial. 2 Timothy 3:16-17 highlights this: "All Scripture is breathed out by God and profitable for teaching, for reproof, for correction, and for training in righteousness, that the man of God may be competent, equipped for every good work." James writes the word of God is implanted and able to save our souls, James 1:21.

Jesus said his words were Spirit and Truth. Jesus is the truth and the word. The Spirit and the Word work together in our new birth, "begotten not from perishable seed rather imperishable through the living and enduring word of God" 1 Peter 1:23.

As believers actively pursue faith and love and "grow in the grace and knowledge of our Lord and Savior Jesus Christ,” 2 Peter 3:18, the supernatural work of God produces fruit of righteousness or obedience. God disciplines his sons, those he chose, adopted, and loves so we share in his divine nature, Hebrews 12:6. 

Jesus said he is the Vine and that like a branch if we abide in him we will bear fruit, John15:4-5. Maturity in Christ that bears fruit of God is really the difference between true obedience which produces works that glorify God and works of self-righteousness.

Being a son is different from being a child. A child needs to be rooted in his spiritual identity, faith, and love, of knowing the Father and that his sins are forgiven, 1 John 2:12-14. A child has testimony from God, “the Spirit himself testifies of our spirit because we exist children of God,” Romans 8:16. It is a son who overcomes, thus is obedient, “for those led by the Spirit of God exist the sons of God.” We see in scriptures maturity from children, to sons, to adults. Fullness is to reach mature adulthood.

This maturity is evidenced by fruit. The fruit of the Spirit is love, joy, peace, patience, kindness, goodness, faithfulness, gentleness, self-control—as listed in Galatians 5:22-23. These qualities are not merely human efforts but supernatural outgrowths of the God work within the heart and transformative renewing of the mind.

To Fullness of God in Christ: The Ultimate Goal

The ultimate trajectory of New Testament growth is nothing less than attaining the "fullness of God in Christ." This profound aspiration is echoed throughout the epistles, particularly in Paul's writings. It speaks to a comprehensive spiritual maturity, a deep intimacy with God, and a profound resemblance to Christ Himself.

Paul prays for the Ephesian believers in Ephesians 3:17-19: "that Christ may dwell in your hearts through faith—that you, being rooted and grounded in love, may have strength to comprehend with all the saints what is the breadth and length and height and depth, and to know the love of Christ that surpasses knowledge, that you may be filled to the fullness of God." 

This "fullness" implies a complete spiritual stature, reflecting the attributes and character of God as revealed in Jesus Christ. It is a state of being completely permeated and controlled by the Spirit, where one's life fully expresses God's purposes and glory.

The goal is not just individual perfection, but also the collective maturity of the Body of Christ. Ephesians 4:13 speaks to this communal aspect: "until we all attain to the unity of the faith and of the knowledge of the Son of God, to mature manhood, to the measure of the stature of the fullness of Christ." 

This vision emphasizes that individual growth contributes to the corporate body reaching its intended potential, reflecting Christ's complete image to the world. This fullness is not a final, static achievement in this life, but an ongoing process culminating in full glorification at Christ's return, where believers will truly be "like him, for we shall see him as he is" (1 John 3:2).

In conclusion, New Testament growth in Christ is a transformative journey that begins with the divine act of new birth, laying an unshakeable foundation in Christ, rooted in faith and love. It progresses through a trying yet refining process of transformation that renews the mind, where maturity is forged through steadfast endurance in trials and faithful obedience to God's Word. 

The ultimate, glorious destination of this spiritual pilgrimage is to be "filled to all the fullness of God," reflecting the very stature of Christ and manifesting His glory, both individually and corporately, until the consummation of all things.

The Crucible

" The LORD will go forth like a warrior, He will arouse His zeal like a man of war. He will utter a shout, yes, He will raise a war cry. He will prevail against His enemies ." 1 He will arouse His zeal like a man of war. The definition of zeal is great energy or enthusiasm in pursuit of a cause or an objective. It is this time, to arouse zeal, shout, raise a war cry! As Paul writes, " In diligence not lagging in spirit being fervent serving the Lord ." 2 Our energy comes in the bond of brotherhood, formed in the crucible of combat. A crucible is place of severe test or trial, it is derived from Latin crucibulum ("night-lamp, metallurgic melting-pot"), and is a derivative of crux ("cross"). 3   The Bible speaks of the crucible of the cross for Jesus and for those who follow Him. The purpose of a soldier is two-fold; to accomplish the mission and to care for one another, as commanded. Each soldier has a role to play on a team. Without knowin...

One Grace

" moreover,  One, to each of us has been given Grace, according to the measure of the gift of Christ ." 1 Grace is a founding principle of Christianity. It is by Grace we grow into the fullness of Christ through faith; " to the measure of the stature which belongs to the fullness of Christ. " 2  Without Grace we will never reach this fullness. The weakness in the Law was it attempted to do it in the flesh, and people failed over and over, so God in His infinite wisdom, unveiled this mystery, through faith in Christ we have grace to boldly approach His throne of Grace, to receive grace and mercy as needed! This gift of Grace is properly understood by examining this verse in three parts;  moreover,  One Grace, to each of us has been given, according to the measure of the gift of Christ . First, we understand,  One   grace, it is easy to miss the  One,  and this verse is translated in different ways, I believe it says One Grace and i...

Those He Calls He Equips

Now may the God of peace who brought again from the dead our Lord Jesus, the great shepherd of the sheep, by the blood of the eternal covenant, equip you with everything good that you may do his will, working in us that which is pleasing in his sight, through Jesus Christ, to whom be glory forever and ever. Amen . Hebrews 13:20-21 When God calls us he equips us, the God of Peace, the one who brought us from the dead by the blood of the Eternal Covenant, will equip you so to do his will. So in this concept of being equipped, we see the calling being irrevocable. "For it is God who works in you to Will and to act on behalf of his good pleasure" ( Philippians 2:13 ).  God called you, he's working in you equipping you to work on behalf of his good pleasure. "So that the man of God may be complete fully equipped for every good work." 2 Timothy 3:17 .  In Hebrews 12 we read God disciplines those he loves, so that we share in his holy character. As the scrip...

Word Of Life

"That which was from the beginning, which we have heard, which we have seen with our eyes, which we looked upon and have touched with our hands, concerning the word of life. " 1 Jesus is the Word, He was in the beginning with God. 2  All things were made through Him. He is the Word and Light of men, the way, the path, "I am the way, the truth, and the life." 4  Thus we can say as the Psalmist, Jesus, the Word, is a Lamp unto my feet, and a Light unto my path. 5  "In him was life, and the life was the light of men." 6  Concerning the Word of Life, " the life was made manifest, and we have seen it, and testify to it and proclaim to you the eternal life ," Proclaimed, that our joy may be complete, a glory like that in the beginning, fellowship with the Father, with one another, and with his Son Jesus Christ, the Word of Life.

The New Living Way

The New Living Way "... Now, at the present released from the Law, having died in that which held us captive, so that we serve in newness of Spirit and not the old written code " -- Romans 7:16 Paul states that we are now united to Christ in his death and also raised with him into newness of life. What held them captive was sin but also the Law, it was a guardian until the appointed time God would send a Messiah (see School Master ). Paul uses the metaphor of marriage to describe how we are released from the Law; like a wife whose husband dies, now she is released from the Law and can marry another, so also have we died with Christ and are released from the Law and bound to Christ in a new covenant. The purpose of this is that we live in a new living way of the Spirit and not fleshly through the old written code or Mosaic Law. " So then brothers, you also have died to the Law through the body of Christ to the extent you exist by creation of another, the one raising you f...

Truth All Around You

Stand then girding your loins in truth and putting on the breastplate of righteousness. * How can a soldier stand in battle if he has not been prepared, trained? How can a house stand if it has been built on sand? How can we stand against spiritual forces if we have not been prepared? Our battle is not against flesh and blood so in regards to such, what good is armor to a child or how can one stained with dirty clothes stand with a defiled conscious? To stand one must be prepared, be his workmanship, someone prepared beforehand to do battle. For this purpose you begin girding your loins in truth, putting on truth, wrapping truth all around you. ... girding your loins in truth... * The word girding is perizōnnymi (from peri "about, around" and zōnnymi "put on") meaning around about put on. Often gird your loins with truth is translated as putting on a belt. Surely we can say truth holds on the garments and confidence in truth is important in standing. I like th...

Putting On the New Self

Putting On the New Self Theme: Spiritual Growth & Identity in Christ Key Scripture: “And to put on the new man, created after the likeness of God in true righteousness and holiness.” — Ephesians 4:24 (ESV) 🕊️ Day’s Reflection The Christian journey is not about becoming a better version of our old selves. It is about walking in The New Living Way , putting on the new man created in the likeness of God. Scripture calls us to put on the new man , and this call is not symbolic or abstract. It is a command grounded in spiritual truth and lived out in daily walking as Christ walked. 📜 Scripture for Meditation 2 Corinthians 5:17 (ESV) “Therefore, if anyone is in Christ, he is a new creation. The old has passed away; behold, the new has come.” Ephesians 4:22–24 (ESV) “To put off your old man, which belongs to your former manner of life and is corrupt through deceitful desires, and to be renewed in the spirit of your minds, and to put on the new man, created after the likeness of...

Called According to His Purpose: A Biblical Examination

  Called According to His Purpose: A Biblical Examination 📖 Introduction The phrase “called according to His purpose” appears in Romans 8:28 (ESV), a foundational verse that reads: “And we know that for those loved of God all things work together for good, for those who are called according to His purpose.” This statement gives comfort and more—it is a declaration about identity, destiny, and divine intent. To be “called according to His purpose” means participating in God’s sovereign, redemptive plan. God's plan is being manifested through the church through the "new covenant in his blood" as it was established by the death of Jesus, his blood. The calling is not arbitrary or based on human merit, but is rooted in God’s purpose, eternal will and love. 🔍 The Nature of the Calling In Scripture, God's calling is effectual—that is, it accomplishes what He intends. Paul writes: "...those whom he predestined he also called, and those whom he called he also...
