Rule-keeping has acquired a bad name in religion. Probably, because man makes rules. And probably, because man rebels even at God’s rules. And possibly, too, because some have removed obedience from the gospel.
Whatever the reasons, and however many they are, it’s in Scripture, both Old and New Testaments.
And Scripture sees the keeping of rules as being dependent on God.
Revive me with your loyal love, that I might keep the rules you have revealed.
God is willing to constantly revive us. The author looks for it, expects it, desires it. His obedience depends upon it. As does ours.
Obedience is a condition to salvation and continued grace. But it also depends upon God’s power and finds in his loyal love motivation more than sufficient to revive the flagging soul.
