9. For the Lord has driven out from before you, etc He intimates that so long as they do not themselves change, there will certainly be no change on the part of God. Therefore he asserts that, provided they conciliate the favor of God, they shall have an uninterrupted course of victory. At length he again exhorts them, as they value their life and safety, to be careful in maintaining love to God. From this source all true obedience springs; for if we do not cling to him with free and ardent affection, we shall study in vain to frame our lives in accordance with the external form of the Law.
