John 3:3-5

3:3 Jesus replied, “I tell you the solemn truth, unless a person is born from above, he cannot see the kingdom of God.” 3:4 Nicodemus said to him, “How can a man be born when he is old? He cannot enter his mother’s womb and be born a second time, can he?”

3:5 Jesus answered, “I tell you the solemn truth, unless a person is born of water and spirit, he cannot enter the kingdom of God.
