My dear MineralMan, for whom I have such esteem: your statement is not true.
"For us men, and for our salvation, He came down from heaven." He made Himself seeable, hearable, touchable. He made Himself physical evidence.
I invite you to look at Post 36 on this thread:

I don't expect you to thwap your forehead and say, "Aha! I agree!" I just want you see that "the very nature of a supernatural entity is that there is no physical evidence of it," which you suppose to be self-evident, practically a tautology, is quite mistaken.
I agree. I might also point out that Jesus is fundamentally different from the gods described by MineralMan as merely a projection of human rules for societal order; Jesus came not to give or enforce laws, but to save us from ourselves and spare us from punishment for breaking the rules.
