It rather depends on what tempts a man. If it's spiritual sins: Pride, bigotry, hatred, envy; then his resistance, all unseen, is heroic.

I'm reminded of the man in Zenna Henderson's "The Closest School" (this is c. late 1950s) who had a gut dislike for foreigners, for those with different skin colors. But he knew what that led to, saw what it did in the world, and so he bent over backward to help the fuzzy pink and green people at his schoolhouse door.

Not because he accepted them, but because he knew he what he had to deny in himself.

A very good man, in my book.
