Actually he has, but I guess you're calling all the people who testify that they seen him liars?

"And without controversy great is the mystery of godliness: God was manifest in the flesh, justified in the Spirit, seen of angels, preached unto the Gentiles, believed on in the world, received up into glory."

"And the LORD spake unto Moses face to face, as a man speaketh unto his friend."

"And Jacob called the name of the place Peniel: for I have seen God face to face, and my life is preserved."

If you don't believe his word, you wouldn't believe even if he came to the earth.

By the way, nice avatar. :thumbsup:
