About Christ ruling in faithfulness:

�with righteousness he will judge the needy, with justice he will give decisions for the poor of the earth. He will strike the earth with the rod of his mouth; with the breath of his lips he will slay the wicked. � Righteousness will be his belt and faithfulness the sash around his waist. � The wolf will live with the lamb, the leopard will lie down with the goat, the calf and the lion and the yearling together; and a little child will lead them. � The oppressor will come to an end, and destruction will cease; the aggressor will vanish from the land. � In love a throne will be established; in faithfulness a man will sit on it-- one from the house of David-- one who in judging seeks justice and speeds the cause of righteousness. � and who through the Spirit of holiness was declared with power to be the Son of God by his resurrection from the dead: Jesus Christ our Lord. � Through him and for his name's sake, we received grace and apostleship to call people from among all the Gentiles to the obedience that comes from faith. � And you also are among those who are called to belong to Jesus Christ. �
