Psalms 119:121
121I have done what is just and righteous. Don’t leave me to my oppressors.
Just and right dealing grounds a plea not to be abandoned to oppressors. Arminian readers find a good-conscience appeal—not sinless perfection, but sincere equity that may ask God’s defense.
Both agree: the oppressed who have not repaid evil may cry for help.
Calvin: he implores help against wicked troublers while testifying the harassment was undeserved. If we would have God succor us, we must meet him with a good conscience. He promises aid to the unrighteously afflicted; the prophet protests he had not provoked enemies, restrained himself from injury, and did not requite evil. Doing judgment at all times means persevering in integrity in public and private.
Conscience testimony accompanies the plea. Integrity is witness, not purchase of grace.
