The fact that we are exhorted again and again to be patient signifies that the acting out of patience is a matter of our wills. No matter how pure our hearts are, we have tests of patience. A pure heart is not an automatic heart, working out things independently of the will. When we have a pure heart, our will is fully set to do right, and through our will we regulate our actions so that they are right. Our feelings are _influenced_ by the will, but are not _controlled_ by it. We can not help feeling sad or joyous when there is an occasion that influences our feelings. So we can not but feel impatient sometimes; that is, things will try our patience, and we find that our feelings respond, in some degree at least, to those circumstances. The degree of response will depend upon our temperament, and the amount of grace we have, and how much we have cultivated patience.
Do not forget that we are not told to feel patient, but to “be patient,” though we should be careful to control our feelings so far as is possible by the force of will. When an impatient feeling comes, we do one of two things: we either yield to it and act it out, or we resist it and act patiently. The latter is what we should always do. When we are full of joy and everything is going smoothly, it is easy to believe that we have plenty of patience; but in time of stress, of trial, when we are weak or suffering in body, when we are weary or feel discouraged, then it is that we most readily feel impatient. It is not that we have less patience at such times, but that impatience more easily manifests itself. We should at all times resist every feeling of impatience, yet we should not condemn ourselves for feeling what we can not help feeling. We should not think that we are not sanctified simply because we are not so patient as we desire to be.
It is natural for a saved person to long for greater patience to endure and suffer. We should do all in our power to grow in patience. “But how shall I add patience?” you may ask. There are two things to do. First, pray; and second, cultivate patience. Make it a practise day by day never to yield to an impatient feeling. Let this attitude be manifested by word and act. Reflect upon the patience of Jesus and study to know what is the Scriptural ideal. When your patience is tried, deliberately take hold of yourself by your will-power and make yourself act and speak as you know you should. By following this rule you will become more and more patient. This is the only possible way of adding patience.
