“The slightest nomism vitiates the gospel. For Paul, grace does not exist on a spectrum. Unlike a dimmer switch, it is binary: ‘grace would no longer be grace’ if works played any role as the ground or instrument of justification (Rom. 11:6).”
–Michael Horton, Justification, Volume 2 (Grand Rapids, MI: Zondervan, 2018), 2: 124.
