Read: Mark 10:17-22 You lack one thing. (v. 21) The rich young man reminds me of myself in too many college classes when I would ask, “Professor, is this going to be on the test?” I wanted the A, and often got it, but missed the learning that came from studying the subject. This young man could check all the boxes when Jesus listed six of the Ten Commandments. The disciples in the crowd likely nodded approvingly, “This guy is good. He must be saved.” What Jesus said next must have surprised them. On Jesus’ grading scale, the man received an incomplete: “You lack one thing” (v. 21). He obeyed all the outward, visible commandments: do not murder, do not steal, and the like. By all accounts, he was a good person, but Jesus knew his heart.
