“When Jesus confronts the world some kind of explosion can be expected; for Jesus and the world are very different, frankly opposite in their purpose, character, values, and aims.
The world is essentially self-centered; Jesus did not come to be served, but to serve, and to give His life a ransom for many (Matt. 20:28). The world is in active rebellion against God; Jesus always pleases His Father (John 8:29).
The world is time-bound and temporary (cf. 1 John 2:15-17); not so Jesus or His kingdom or the person who does His will. The world needs saving, and Jesus comes to save His people from their sins (Matt. 1:21).
The world needs judging, and Jesus is the Son of man who comes when least expected and passes the entire world under review (Matt. 24:36-25:46). Jesus and the world are bound to clash with each other.”
