"The power of Christ alone can work the transformation in heart and mind that all must experience who would partake with Him of the new life in the kingdom of heaven. “Except a man be born again,” the Saviour has said, “he cannot see the kingdom of God.” John 3:3 . The religion that comes from God is the only religion that can lead to God. In order to serve Him aright, we must be born of the divine Spirit. This will lead to watchfulness. It will purify the heart and renew the mind, and give us a new capacity for knowing and loving God. It will give us willing obedience to all His requirements. This is true worship. 9T 156.1"
"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."
