John 3:7 Marvel not that I said unto thee, Ye must be born again. When Jesus told Nicodemus that except a man be born again he cannot see [perceive] the Kingdom of God as per vs 3 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. In essence, what Jesus meant, except ye are of that seed in Me, by being Chosen in Him before the foundation of the World [Eph 1:4] ye cannot see or understand the Kingdom of God, which is to include it's Gospel, The Gospel of the Kingdom or of the Kingdom of God. Matt 24:14 And this gospel of the kingdom shall be preached in all the world for a witness unto all nations; and then shall the end come. Mark 1:14 Now after that John was put in prison, Jesus came into Galilee, preaching the gospel of the kingdom of God, Which are also the Kingdom Mysteries Luke 8:10 And he said, Unto you it is given to know the mysteries of the kingdom of God: but to others in parables; that seeing they might not see, and hearing they might not understand. Now, even though Jesus was giving a condition " except ye be born again ", yet He was not giving a imperative or duty for one to perform to become born again; because there is nothing a person can do to be born; even if it was for us to go back into our mothers womb, [ which its not] how could we accomplish that ? Could we make ourselves fetuses again ? Would that be in our ability ? But nevertheless, Christ meant what He said in stating that 'Ye must be born Again " !
