When I Am Tempted

The temptations of Jesus are many because, like pain, he experienced every kind. More than any other attribute, the thing that most differentiates Jesus the Christ from mortal man was how he responded when temptation came. He suffered every temptation but gave into none of them.

Studying the life and mission of Jesus Christ, and binding ourselves to him through covenant fortifies our power over the temptations we face. His resolve to be without sin, though tempted, is the reason he could be without blemish, the Lamb of God, who takes away the sins of the world.

What does it mean to overcome the world? It means overcoming the temptation to care more about the things of this world than the things of God. It means trusting the doctrine of Christ more than the philosophies of men. It means delighting in truth, denouncing deception, and becoming “humble followers of Christ.” It means choosing to refrain from anything that drives the Spirit away. It means being willing to “give away” even our favorite sins.

No man knows how bad he is till he has tried very hard to be good. A silly idea is current that good people do not know what temptation means. This is an obvious lie. Only those who try to resist temptation know how strong it is. After all, you find out the strength of the German army by fighting against it, not by giving in. You find out the strength of a wind by trying to walk against it, not by lying down. A man who gives in to temptation after five minutes simply does not know what it would have been like an hour later. That is why bad people, in one sense, know very little about badness. They have lived a sheltered life by always giving in. We never find out the strength of the evil impulse inside us until we try to fight it: and Christ, because He was the only man who never yielded to temptation, is also the only man who knows to the full what temptation means — the only complete realist.
