Jesus asked his followers, “Who do you say I am?” Simon Peter answered, “You are the Messiah, the Son of the living God.” Jesus replied, “You are blessed, Simon son of John, because my Father in heaven has revealed this to you. You did not learn this from any human being.
From then on Jesus began to tell his disciples plainly that it was necessary for him to go to Jerusalem, and that he would suffer many terrible things at the hands of the elders, the leading priests, and the teachers of religious law. He would be killed, but on the third day he would be raised from the dead. But Peter took him aside and began to reprimand him for saying such things. “Heaven forbid, Lord,” he said. “This will never happen to you!” Jesus turned to Peter and said, “Get away from me, Satan! You are a dangerous trap to me. You are seeing things merely from a human point of view, not from God’s.”
— Matthew 16:15-17, 21-23
I am amazed at the ability of Simon Peter to be so smart and so dense in such quick succession. In one scenario Jesus commends him saying he has heard what he knows the from the Lord. In the next scenario from mere days later Jesus reprimands him for seeing things from a human instead of divine view. It is quite amazing that one person could be so right at one point and then so wrong in almost the very next breath.
But somehow I don’t think Peter is unusual in his glimmers of insight or frustrating obtuseness. I myself have this same ability to be so bang on in one minute and so far off in the next. At one point it can seem as if I am listening to God’s voice and saying all the best things and the next I could be saying something totally stupid and out of line with God’s plans and purposes.
Such is the human struggle.
