There is no question that obedience to God’s commands prompted by fear or merit-seeking is not true obedience. The only obedience acceptable to God is constrained and impelled by love, because “love is the fulfillment of the law” (Romans 13:10). God’s law as revealed in His Word prescribes our duty, but love provides the correct motive for obedience. We obey God’s law, not to be loved, but because we are loved in Christ.
