God sometimes picks out people according to their natural tempers, and employs them in his work. Jehu, a man of a furious temper, and ambitious spirit, is called out for the destruction of Ahab’s house. Moses, a man furnished with all Egyptian wisdom, fitted by a generous education, prepared also by the affliction he met with in his flight, and one who had had the benefit of conversation with Jethro, a man of more than ordinary wisdom and goodness, as appears by his prudent and religious counsel, he is called out to be the head and captain of an oppressed people, and to rescue them from their bondage, and settle the first national church in the world. So Elijah, a high-spirited man, of a hot and angry temper, one that slighted the frowns and undervalued the favour of princes, is set up to stem the torrent of the Israelitish idolatry. So Luther, a man of the same temper, is drawn out by the same wisdom to encounter the corruptions in the church, against such opposition, which a milder temper would have sunk under.
