In respect to justification, grace stands opposed to works (Rom. 4:4-5; 11:6). However, in respect to sanctification, grace is the source of works. This simply means that whereas we are saved by grace and not of works, we are saved by grace unto good works. Good works are the fruit, not the root, of God’s saving grace (see esp. Eph. 2:8 -10).
