125:1-3 All those minds shall be truly stayed, that are stayed on God. They shall be as Mount Zion, firm as it is; a mountain supported by providence, much more as a holy mountain supported by promise. They cannot be removed from confidence in God. They abide for ever in that grace which is the earnest of their everlasting continuance in glory. Committing themselves to God, they shall be safe from their enemies. Even mountains may moulder and come to nothing, and rocks be removed, but God's covenant with his people cannot be broken, nor his care of them cease. Their troubles shall last no longer than their strength will bear them up under them. The rod of the wicked may come, may fall upon the righteous, upon their persons, their estates, their liberties, their families names, on any thing that falls to their lot; only it cannot reach their souls. And though it may come upon their lot, it shall not rest thereon. The Lord will make all work together for their good. The wicked shall only prove a correcting rod, not a destroying sword; even this rod shall not remain upon them, lest they distrust the promise, thinking God has cast them off.
3. Though God may leave them for a time under the "rod," or power (Ps 2:9), and oppression of the wicked for a time, as a chastisement, He will not suffer them to be tempted so as to fall into sin (1Co 10:13). The wicked shall only prove a correcting rod to them, not a destroying sword; even this rod shall not remain ("rest") on them, lest they be tempted to despair and apostasy (Ps 73:13, 14). God may even try His people to the uttermost: when nothing is before our eyes but pure despair, then He delivers us and gives life in death, and makes us blessed in the curse (2Co 1:8, 9) [Luther].
the lot—the possession, literally, "Canaan," spiritually, the heavenly inheritance of holiness and bliss which is appointed to the righteous. Sin's dominion shall not permanently come between the believer and his inheritance.
