If one were to take the Bible very literally as some folks do with regard to the scripture that says a thousand years is but one day to God, then the notion that God would send his "son" down to earth when He did IMO doesn't seem too brilliant a move on God's part.
I can picture Jesus saying "Hey Dad, if we wait a couple of days we can do this LIVE on CNN. Maybe You could pull a few strings and I could get on Larry King Live, maybe even the Tonight Show...you know, do a couple of miracles and the whole crucification thing live via satellite - the whole world could see it all at once - if we do it YOUR way it could take a couple thousand human years to spread the GOOD NEWS
