When the disciples reached the other side, they had forgotten to bring any bread. Jesus said to them, “Watch and beware of the leaven of the Pharisees and Sadducees.” And they began discussing it among themselves, saying, “We brought no bread.” But Jesus, aware of this, said, “O you of little faith, why are you discussing among yourselves the fact that you have no bread? Do you not yet perceive? Do you not remember the five loaves for the five thousand, and how many baskets you gathered? Or the seven loaves for the four thousand, and how many baskets you gathered?” (Matthew 16:5-10)
The first time that Jesus fed thousands of people with a few loaves and a few fish, the disciples doubted, and it was somewhat understandable. The second time, they doubted again, and it was surprising, given what they had seen before. Now, when they forgot bread, and Jesus begins to warn them about the spiritual leaven of the unbelieving Jewish leaders, they think He’s talking about physical bread, and they doubt Him yet again. This time, it’s almost comical. They saw over nine thousand people fed with twelve loaves of bread, with plenty of leftovers, and still they doubted.
I say it’s “almost comical”, (1) because sin isn’t funny and (2) when I take a sober look at myself, I’m pretty much like these disciples. I have seen God do amazing wonders throughout my life, and yet in even small daily matters, I falter in my trust of Him. Let us not be like these disciples, marveling at the incomparable power of God in one moment, and doubting it the next.
