35 And a certain man of the sons of the prophets said to his fellow at the command of the Lord, "Strike me, please." But the man refused to strike him. 36 Then he said to him, "Because you have not obeyed the voice of the Lord, behold, as soon as you have gone from me, a lion shall strike you down." And as soon as he had departed from him, a lion met him and struck him down. 37 Then he found another man and said, "Strike me, please." And the man struck him--struck him and wounded him. 38 So the prophet departed and waited for the king by the way, disguising himself with a bandage over his eyes. 39 And as the king passed, he cried to the king and said, "Your servant went out into the midst of the battle, and behold, a soldier turned and brought a man to me and said, 'Guard this man; if by any means he is missing, your life shall be for his life, or else you shall pay a talent[1] of silver.' 40 And as your servant was busy here and there, he was gone." The king of Israel said to him, "So shall your judgment be; you yourself have decided it." 41 Then he hurried to take the bandage away from his eyes, and the king of Israel recognized him as one of the prophets. 42 And he said to him, "Thus says the Lord, 'Because you have let go out of your hand the man whom I had devoted to destruction,[2] therefore your life shall be for his life, and your people for his people.'"

(Read 1 Kings 20:31-43)
This encouragement sinners have to repent and humble themselves before God; Have we not heard, that the God of Israel is a merciful God? Have we not found him so? That is gospel repentance, which flows from an apprehension of the mercy of God, in Christ; there is forgiveness with him. What a change is here! The most haughty in prosperity often are most abject in adversity; an evil spirit will thus affect a man in both these conditions. There are those on whom, like Ahab, success is ill bestowed; they know not how to serve either God or their generation, or even their own true interests with their prosperity: Let favour be showed to the wicked, yet will he not learn righteousness. The prophet designed to reprove Ahab by a parable. If a good prophet were punished for sparing his friend and God's when God said, Smite, of much sorer punishment should a wicked king be thought worthy, who spared his enemy and God's, when God said, Smite. Ahab went to his house, heavy and displeased, not truly penitent, or seeking to undo what he had done amiss; every way out of humour, notwithstanding his victory. Alas! many that hear the glad tidings of Christ, are busy and there till the day of salvation is gone.
