" In addition to the great christological implications, this passage discloses something of the nature of the kingdom into which Christians have been drawn, and therefore of the conduct that is demanded of us. On the one hand, as Matthew has made clear in the previous chapter, Jesus' witnesses are called to a holy and courageous boldness, a firm fidelity to the Gospel that is willing to endure ostracism and even persecution. But we are not to display the kind of "strength" that is hard and harsh, the kind of uprightness that is angry and condescending, the kind of courage that is merely ruthless, the kind of witness that rants and manipulates.
