Jesus only said that to one person- Nicodemus. He also said that the truth of who he is can only be revealed by the Holy Spirit, not by flesh and blood. If you think about it and read the gospels, the disciples did not know who Jesus REALLY was until after He went back to heaven- even though they lived with him for 3 years...so, why do we have such impatience with others who don't know yet? If we just lift up Jesus (as opposed to Christianity) all men will come....
If they, all come, then revealed prophecy is WRONG...
They will NOT all come..
