From John Stott:
One of the most extraordinary things Jesus did in his teaching (and did it so unobtrusively that many people read the Gospels without even noticing it) was to set himself apart for everybody else. For example, by claiming to be the good shepherd who went out into the desert to seek his lost sheep, he was implying that the world was lost, that he wasn’t, and that he could seek and save it. In other words, he put himself in a moral category in which he was alone.
Everybody else was in darkness; he was the light of the world.
Everybody else was hungry; he was the bread of life.
Everybody else was sinful; he could forgive their sins.
Indeed, on two separate occasions he did so, and both times observers were scandalized. They asked, “Why does this fellow talk like that? He’s blaspheming! Who can forgive sins but God alone?” (Mark 2:5-7; Luke 7:48-49)
If Jesus claimed authority to forgive the penitent, he also claimed authority to judge the impenitent. Several of his parables implied that he expected to return at the end of history. On that day, he said, he would sit on his glorious throne. All nations would stand before him, and he would separate them from one another as a shepherd separates his sheep from his goats. in other words, he would settle their eternal destiny. Thus he made himself the central figure on the day of judgment.
