Here is certainly a motive of a very powerful kind. Which of us would dare to cherish the bitter thought, or proceed with our plan of vengeance, if we remembered and realized that our vindictiveness would make our own pardon at the hands of God impossible? Which of the countless deeds of retaliation that stain with blood the pages of history would have been perpetrated, and which of the perpetrators would not have tremblingly relinquished all thought of reprisals, if they had seen that in those savage acts of vengeance they were not, as they supposed, executing lawful justice, but actually cutting off their own hope of pardon before the throne of God?
If we avenge ourselves, if society is constantly torn by the quarrels and the mutual recriminations of hostile men whose one thought is to give as good as they have got, it can only be because we do not believe, or do not realize, this solemn teaching of the Lord. He seems a faint and doubtful voice compared with the loud tumult of passion within; His authority seems weak and ineffectual compared with the mighty domination of the evil disposition. Powerful, therefore, as the motive is to which He constantly appeals, if He had left us nothing but His teaching on the subject we should not be materially better off than they who listened with attention to the teaching of the wise authors of these ancient Proverbs. What more has He left us?
It is His prerogative to give to those who believe in Him a changed heart. How much is meant by that, which only the changed heart can know! Outwardly we seem much alike; outwardly there is little sign of an inward transformation; but far as the east is from the west is the unregenerate heart from the regenerate, the Christless heart from one which He has taken in His hands, and by His great redemption created anew. Now without stopping to follow the processes of faith by which this mighty change is effected, let us simply mark the characteristics of the change so far as it affects the matter in hand.
The first and most radical result of the New Birth is that God takes the place which Self has occupied. All the thoughts which have clustered about your own being now turn to His Being, as stray fragments of iron turn to the magnet. Consequently, all the emotions and passions which are stimulated by self-love give place to those which are stimulated by the love of God. It is as if the pipes of your aqueduct had been changed at the fountain head, disconnected from the malarious waters of the marsh, and connected with the pure and sparkling water of the hills. God's ways of regarding men, God's feelings towards men, His yearning over them, His pity for them, flow into the changed heart, and so preoccupy it that resentment, hatred, and malice are washed out like the sour dregs in a cup which is rinsed in a running stream.
There is the man who did you the wrong--very cruel and unpardonable it was!--but, as all personal elements are quite out of the question, you regard him just as if you were not the injured being. You see him only as God sees him; you trace all the malignant workings of his mind; you know how the fire of his hate is a fire which burns the heart that entertains it. You see clearly how tormenting those revengeful passions are, how the poor soul mastered by them is diseased, how the very action in which it is triumphing now must become one day a source of bitter regret and implacable self-reproach; you soon begin to regard the ill deed as a shocking wound inflicted on the doer of it, and the wells of pity are opened. As if this enemy of yours had been quite innocent of all ill-will, and had been overtaken by some terrible calamity, your one instinctive thought is to help him and relieve him. Out of the fulness of your heart, without any sense of being magnanimous, or any thought of a further end,--simply for the pity of it,--you come to proffer him bread in his hunger and water in his thirst.
