A child of God is one who is born of the Spirit and focuses on spiritual things. _Meanwhile, John 3:3-7 says anyone who wants to enter into the kingdom of God must be born of the Spirit.
It is the kind of fruit you produce that will determine who your father truly is. -Galatians 5:22-23

Memorise: Wherefore by their fruits ye shall know them. -Matthew 7:20
