When Jesus calls, he calls us one by one. Comparisons are idle, speculations about others a waste of time, and envy as silly as it is evil. We are each called individually, accountable to God alone, to please him alone, and eventually to be approved by him alone. If ever we are tempted to look around, compare notes, and use the progress of others to judge the success of our own calling, we will hear what Peter heard: "What is that to you? Follow me!"
