Psalms 124:1
1If it had not been the LORD who was on our side, let Israel now say,
If the LORD had not been on our side—let Israel say it aloud. Corporate memory opens with a conditional that drives thanksgiving, not idle speculation about what might have been.
Classical Arminians find a people invited to confess deliverance together. God truly sided with them in trouble; they freely join the refrain that keeps gratitude awake on every ascent.
If the LORD had not been on our side—Israel must say so. The counterfactual exposes how completely safety hung on God's presence with His covenant people, not on their skill.
Being "on our side" is covenant initiative. The church's survival past rising foes is not a near-miss of luck but the LORD's prior commitment to those He claims as His own.
Key contrast Both urge Israel to confess that only the LORD's being "on our side" explains survival. Arminians press a welcomed siding with those who trust Him; Reformed interpreters stress God's covenant commitment that precedes and explains the people's escape.
