It’s in the mysteries of God, man is made into God’s own image.
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. John 3:3
Standing before Nicodemus Jesus said, “Except a man be born again, he cannot see the kingdom of God.” Jesus could see the confusion and bewilderment on Nicodemus’ face so much so that He had to explain His comments further. So, Jesus said, “Except a man be born of water and of the Spirit, he cannot enter into the kingdom of God.” Jesus told Nicodemus; obviously you must be born just like every other person in this world, of flesh and blood. The He goes on to explain the second birth, salvation. Without the second birth no one will enter into Heavens gates. The second birth is why Jesus came. The second birth is why He died. The second birth is why He arose from the grave. The second birth is why He lives today!
Here it is one more time for you; “Marvel not that I said unto thee, Ye must be born again.” John 3:7
