This marking or sealing is to the extent of His own, as Paul writes in a previous verse, he predestined us for adoption as his own (Ephesians 1:4).

We are birth into the kingdom of God through the Spirit and this occurs when we hear and believe the gospel. I tell you the solemn truth, unless any is born anew he can't see the kingdom of God...
