There is no such thing as cheap love. Our sinful condition, our situations of envy, jealousy, hostility, anger, can be transformed only by love. The human situation is too badly out of hand to be overcome by our tugging at our own boot straps. God's first work in and for us is, by loving He gives us the power and the capacity to love. God's love changes us into loving persons.
Love is both response and responsibility.
Obedience isolated from love tends toward legalism. Then we take our motivation from the law and not from love. We can never relax our grip on the claims of tire Ten Commandments and our need to obey them. Obedience without love means obedience to the letter of the law, the imposition of rules and regulations from without. In such obedience formal conformity to the law is the main thing.
