Q. When Satan took Jesus up the the heights and promised him the world if he would fall down and worship him…why would Jesus have been tempted to worship Satan?
We do usually think of “temptation” as what happens when our desire for something becomes so irresistible that we’re inclined to make some moral compromise to get that thing. That picture does apply to the other two temptations that the devil offered Jesus, though it doesn’t quite apply to the one you’re asking about. (The temptation of Jesus by Satan is described near the beginning of the gospels of Matthew, Mark, and Luke.)
We can understand, for example, how Jesus would have had a strong desire for food after fasting for 40 days in the wilderness. Ordinarily there’s no compromise involved in satisfying a legitimate physical need within the limits of moderation. But in this case Jesus had been called to an extended time of fasting so that he could consider the implications of the voice he’d just heard at his baptism, “This is my beloved son, in whom I am well pleased.” He was called, in other words, to reflect on the nature of his calling to be the Messiah, which most interpreters say was confirmed definitively for him by this voice at his baptism. So it would have been a compromise to break that fast prematurely just because he was hungry, or just to prove that he had God’s favor. (“If you are the Son of God, command these stones to become bread,” the devil had said.)
Similarly, leaping off the highest point of the temple and landing safely on the ground might actually have been something that appealed to Jesus. He was a 30-year-old single man and we can well imagine that he might have gone in for extreme sports! It would be like bungee jumping, with the assurance of God’s power of deliverance providing the same confidence and security as a bungee cord. However, Jesus recognized that it would have been improper to put himself in danger just to prove that God would protect him. We are supposed to do our part to care for ourselves, and we’re supposed to trust in God by faith, without needing proof of God’s care when we’re not in any real danger.
But the third temptation was different. Jesus wouldn’t have found it desirable to worship Satan. So what the devil actually tried to tempt him with was power over all the kingdoms of the world. “Just think of all the good you could do if you had that power,” was the subtle lure. Satan’s pitch was that worshiping him would simply be a “necessary evil,” a means to a desirable end. The fallacy, of course, is that if we compromise to get into a position of power, then we’re compromised once we get there, so we can’t do the good we intended. This would certainly have been the case for Jesus if he’d tried to get power by literally selling his soul to the devil.
So the takeaway is that we aren’t always “tempted” by things that seem desirable, attractive, or alluring. Sometimes unpleasant things “tempt” us because we think of them as a means to an end. But God always has a better means to any legitimate end, a means that doesn’t require moral compromise.
