Hello. Well I don't know if I can say what he was REALLY saying, I'm not Jesus. But I'll give it a shot. You may relate this phrase to the title of a "born again christian". The belief being that they now see the kingdom of God because they have been saved by Jesus and therefore, "born again". Rebirth can mean almost anything, metaphorically, such as rejuvenation or simply a change in thought. The gist of the saying is that, until a man changes his thoughts to the ways of God and light, he will not see the final kingdom. Thank you and Good bye.
