Satan is not senseless or unintelligent. He knows very well that if temptation was not tempting no-one would fall for it. Temptation is always inviting, alluring and appealing. We are always tempted by that which seems to be so good and promising. Or as Revelation 17 says, temptation is like a golden cup, which looks attractive, but is actually “full of abominations” and “impurities” (Revelation 17:4).
