[3] Let us take heed, for mercy is like a rainbow, which God set in the clouds to remember mankind: it shines here as long as it is not hindered; but we must never look for it after it is night, and it shines not in the other world. If we refuse mercy here, we shall have justice there.--_Jeremy Taylor,_ 1612-1667. THE PURPOSE OF PUNISHMENT. i. 24-27. _Therefore thus saith the Lord, the Lord of hosts, the Mighty One of Israel, Ah, I will ease me of mine adversaries, and avenge me of mine enemies: and I will turn mine hand upon thee, and purely purge away thy dross, and take away all thy tin: and I will restore thy judges as at the first, and thy counsellors as at the beginning: afterwards thou shall be called, The city of righteousness, The faithful city. Zion shall be welcomed with judgment, and her converts with righteousness._ The denunciation of the iniquity of Jerusalem (vers. 21-23) is followed by a solemn announcement of God's determination to punish it. +I. God will certainly punish sin.+ "Ah, I will ease me of mine adversaries, and avenge me of mine enemies." See preceding outline, and that on verse 20. +II. In punishing sin God is not moved by any vindictive purpose.+ True, He speaks here of taking vengeance upon His enemies, but these words coming from the lips of Jehovah must not be interpreted as we should have to interpret them if they came from the lips of a Genghis Khan or a Tippoo Saib. We must remember that this is the utterance of the Mighty One of Israel, who is infinitely uplifted above every unholy passion. Whatever misconstruction the phrase, taken alone, might be open to, is entirely obviated by the declarations which follow it, which teach us--+III. That God's aim even in the severest chastisements is the reformation of the offenders, and their restoration to true blessedness.+ For what purpose will He turn His hand upon Jerusalem? Not that He may destroy her, but that He may purify her, as silver is purified in the furnace; and through this painful process she is caused to pass, that she may be restored to her former dignity and blessedness. It is for these purposes that God chastises nations and individuals to-day.
