Then he returned to his disciples and found them sleeping. “Couldn’t you men keep watch with me for one hour?” he asked Peter. “Watch and pray so that you will not fall into temptation. The spirit is willing, but the flesh is weak.” Matthew 26:40, 41
If I’m going to make an honest assessment based on my history, when I’ve fallen, it wasn’t because the flesh was weak (although it was). It goes deeper than Peter’s struggle. Rarely have I stumbled into sin with my eyes closed. I usually know what I’m doing.
I’m doing what I want to do in that moment. It may be an unkind word, a bit of resentment, a stretch of the truth, a parcel of pride, a vein of vanity, a shred of condemnation. All are indulgences that aren’t a result of the weakness of my flesh. They’re a result of a profound ability to rationalize, at best, and a state of indifference at worst.
Most often, I’ve fallen because my spirit wasn’t willing. Of course my flesh is weak. That’s my nature. It always will be and so I’ll always need to watch and pray. But when my spirit isn’t willing, God won’t crush it and force His will on me. He calls and He waits. Grace is His calling card. That’s His way.
