For while your obedience is known to all, so that I rejoice over you, I would have you wise as to what is good and guileless as to what is evil.
In the world, the notion of “wisdom” is uniformly wrong. To “get wise” in the world is always to lose one’s innocence, for the world routinely divides people into two classes: the evil and the stupid. In the kingdom of heaven, however, this Darwinian model of clever predator and stupid prey gives way to a higher reality: sacrificial love. In the kingdom, we become wise, not by learning the folly of selfishness and exploitation of others, but by living the love of Christ and the wisdom of the cross.
