John 3:3; John 3:5; John 18:36

3 Jesus answered and said unto him, Verily, verily, I say unto thee, Except a man be born again, he cannot see the kingdom of God.
5 Jesus answered , Verily, verily, I say unto thee, Except a man be born of water and of the Spirit, he cannot enter into the kingdom of God.
36 Jesus answered , My kingdom is not of this world: if my kingdom were of this world, then would my servants fight , that I should not be delivered to the Jews: but now is my kingdom not from hence.
