But to all who believed him and accepted him, he gave the right to become children of God.   They are reborn—not with a physical birth resulting from human passion or plan, but a birth that comes from God.     John 1:12-13 

Everyone who believes that Jesus is the Christ has been born of God, and everyone who loves the Father loves whoever has been born of him.  For everyone who has been born of God overcomes the world.  And this is the victory that has overcome the world—our faith. 
1 John 5:1, 4 

2 Corinthians 5:17. Therefore it any man be in Christ he is a new creature.  Old things are passed away behold everything has become new.
