Be born again unless you cannot see or enter the kingdom of God.
Jesus answered and said unto him, verily, verily, I say unto thee; except a man is born again he cannot see the kingdom of God. Nicodemus said unto him, how can a man be born again when he is old? Can he enter the second time into his mother’s womb and be born? Jesus answered, “Most assuredly, I say to you, unless one is born of water and the Spirit, he cannot enter the kingdom of God.” John 3:3-5.
A man born once is bound to die again. But a man born twice will live forever. The kingdom is open for you; you can only see what you believe.
