1 John 5:3
The commandments tell us how to express the love of God. They tell us what form our efforts are to take to express this love and how it is to be directed towards both God and man. The first four commandments are primarily directed at God, while the last six are directed at man. Therefore, what we see is a channel that our loving conduct is supposed to take. In one sense, this is where the love of God commences in a human being—when he begins keeping the commandments.
A person may have a thought to do good or to refrain from evil. He may have a feeling of compassion or pity or mercy—or a feeling of revulsion to something that is evil. However, it does not become love until the thought or the feeling motivates the person to act. Love is an act.
Then another aspect of love comes into play. This kind of love can be done coldly, reluctantly, or out of dutiful obligation. On the other hand, it can be done in joyous, wholehearted submission, with a great deal of enthusiasm, warm-heartedly, and with thankful devotion, or anywhere in between. Because of this, we have to ask, "Which is more attractive?" Love that is done in warm-hearted enthusiasm or coldly, reluctantly, or dutifully?
It is better to do an act of obedience, regardless of the feeling, than not to do it at all. Nonetheless, if we cannot get beyond the feeling that it is right, the proper feelings will never be formed, because emotions are largely developed by experience. This is important: The right emotions will never be formed without experiencing the right actions with the right spirit—God's Holy Spirit.
