"13Enter ye in at the strait gate: for wide is the gate, and broad is the way, that leadeth to destruction, and many there be which go in thereat: 14Because strait is the gate, and narrow is the way, which leadeth unto life, and few there be that find it."

"3Jesus answered and said unto him, Verily, verily, I say unto thee, Except a man be born again, he cannot see the kingdom of God.
4Nicodemus saith unto him, How can a man be born when he is old? can he enter the second time into his mother's womb, and be born? 5Jesus 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. 6That which is born of the flesh is flesh; and that which is born of the Spirit is spirit. 7Marvel not that I said unto thee, Ye must be born again."
