Read Hebrews 4.
Jesus had it easy, right? Sure, he had to contend with the limitations of human nature during his days on earth. But since he was God he did not have to worry about being “hardened by sin’s deceitfulness” (3:13). He knew what a liar Satan is and how sin offers us pleasure that it cannot ultimately deliver, at least not for long. So it was easy for him to live the faithful life that chapter 3 talked about, right?
At least, it was easier for him than it is for us, it seems. So the statement here in 4:15 that our high priest “has been tempted in every way, just as we are—yet he did not sin” feels a bit hollow, yes?
Well…, think about it this way: imagine you are running a marathon-26.2 miles. Some people drop out after a mile, some after five miles, some quit 10 miles in, and so on. You’ve done some training and are in the best shape of your life, but from mile 10 onward your legs are just screaming to you, “Stop it!”
You have the ability to quit at any time.
You can drop out of the race anywhere.
So who feels punishment of running the most, the person who completes the entire race or the one who drops out after a mile? Who feels the discomfort of high winds the most, the runner who quits at mile 5 or the one who finishes the race? What about the hot sun? Who gets burned the worst, the runner who quits after the finish line or the one who quits at mile 15? Whose foot blisters hurt the most? Who suffers most from the internal arguments that your brain engages in to try to get you to quit?
All of these problems are felt most acutely by the runner who completes the race. Whether he or she is in better shape than you or not, the toll of the race is felt most fully by the one who completes it.
Similarly, when I was in seminary my systematic theology professor said that only the one who withstands temptation completely knows the full force of it. If you give into temptation before the temptation goes away, you haven’t experienced the full intensity of it.
So Jesus, the “one who has been tempted in every way, just as we are—yet he did not sin” (v. 15b) is able to “empathize with our weaknesses” (v. 15a) fully because he successfully endured every scheme the devil had to throw at him.
Sure Jesus had a perfect nature but so did Adam and he quit after the first half mile. Jesus, however, endured every temptation obediently. He finished the race so he felt the difficulty of it more than anyone else who has ever lived.
This is why the author of Hebrews urges us to “approach God’s throne of grace with confidence, so that we may receive mercy and find grace to help us in our time of need” (v. 16).
You may be tempted to throw your faith away (v. 14c) at some point in your life; in fact, you probably will be tempted to do that somewhere along the way.
But the best thing you can do when you feel tempted to sin in any way is to go to Jesus in prayer. Many of our failures to live a holy life by resisting temptation are due to relying completely on ourselves and our willpower instead of coming to Christ for the mercy and grace he offers. So, go to him in prayer when your faith is weak and your desire to sin is strong.
He’s finished the marathon, he knows what it is like, and he will help you if you ask him for it.
