Isaiah 62:1
1For Zion’s sake I will not hold my peace, and for Jerusalem’s sake I will not rest, until her righteousness shines out like the dawn, and her salvation like a burning lamp.
Wesley: Zion and Jerusalem are both put for the church (Heb 12:22). These seem to be the words of the prophet strongly resolving, notwithstanding all difficulties, to solicit God for the church’s happiness, and constantly excite to the belief of it by his preaching. Righteousness—the vindicating of his people’s cause; the lamp is the church conspicuous among the nations, and the revealing of Christ unto the world.
The church still prays and preaches until righteousness shines. Silence is not obedience. Zion first; the gospel church is the same people. Shared ground with Calvin: he will not rest till her salvation burns.
Calvin: some explain this as relating to prayer, but he refers it rather to doctrine. The prophet will not be slack till he encourage believers in the hope of salvation. Teachers spend themselves for the Church. Righteousness is the Church’s rights restored; salvation is added, because those God justifies regain their salvation.
God will execute his promises at the proper time. We are wretched while his grace is withheld for sin. Same persistence as Wesley; the accent is the effectual word God owns.
