Casting all your anxiety on him because he cares about you (1 Peter 5:7)
Look at the birds of the air; neither do they sow nor reap nor gather in storehouses, and your heavenly Father feeds them. Are you not much more valuable than them? (Matthew 6:26-34)
Birds don't sow to have seed to eat later, they don't gather food for the winter, yet God feeds them. Look at the lilies and how they grow, not toiling nor spinning. If he cares for the birds and clothes the flowers in such glory, how much more will he value and care for you? What do you have to be anxious about if you know he cares about you?
If men being bad know how to give good things to their children how much more will God give good things to his children who ask. And if we ask for bread will he give us a stone? We know that caring for someone is loving them. We see this when Jesus asked Peter if he loved him three times. Do you love me? Take care of my sheep and lambs.
It is easy to think God doesn't care because of the circumstances of this life that he allows us to go through which are not always pleasant. But often being transformed from glory to glory is that which is revealed to us through the trial. "For I reason this; because the sufferings of the present time are not of equal value compared to the glory, that about being revealed to us" (Romans 8:18). Knowing we begin to realize that God doesn't prove that he cares for us through earthly prosperity or an easy life, but in ways more precious than silver or gold.
he who did not spare his own son but delivered him up for us all, how will he not also graciously give together with him, give us all? (Romans 8:32)
Loving him begins with knowing him, his love, "This is love: not that we loved God, but that he loved us and sent his Son as an atoning sacrifice for our sins" (1 John 4;10). He cares, he is working out all things for our good, to those called according to his purpose, to those "loved of him." He loves and cares about you.
