Here then is the mode of God’s power, and we know that it can be no other; for if God is truly King, He must be King of our hearts and wills, and not only of our conduct. There is only one way to win men’s hearts and wills, that is by showing love; and there is only one way to show love, and that is by sacrifice, by doing or suffering what, apart from our love, we should not choose to do or suffer. Sacrifice is the Divine activity; Calvary is the mode of the Divine omnipotence. It is the actual Divine method and the ideal human method. As we come to consider how far it has become also the actual human method, we are confronted at the outset by the sheer impossibility of our applying this method, just because we have not in ourselves the necessary love. Our perfection, we are told, is to consist in just that quality which shows the Father’s perfection, namely, that He is kind to the unthankful and evil, and makes His sun to rise on the evil and good and sends His rain on the just and on the unjust; and we are to be perfect in the way that He is perfect.[#] [#] S. Matthew v, 43-48. But until we reach that perfection we cannot imitate His action; for a man’s act is not what He intends; nor is it the mere motion of his body; but it is the whole train of circumstances that he initiates. Christ in His perfect purity may stand before the woman taken in her sin and say, "Neither do I condemn thee," because there is no possibility that she will interpret His mercy as condonation of the sin; but if we said it, people would so interpret it, and usually quite rightly so. Our problem then is so to guide our conduct that we come as near as we are capable of coming to the divine ideal that is set forth in Christ, and that we come perpetually closer and closer to it. The Lord in His temptation rejected all use of force and substituted for it the appeal of love expressed in sacrifice, so far as the actual and positive building of His Kingdom is concerned. For us there must always be some use of the lower method, because we are incapable of applying the highest. If any man, when he is confronted with evil which he can prevent by the exercise of force, refrains from doing it, we must immediately put to him the question, "But did you so suffer under that act of evil that there is any hope of your suffering proving to be the redemption of the evil-doer? If so, well and good; but, if not, then you are idle and cowardly, not Christian." No one who is not a Christian in spirit can perform the Christian act; and the Sermon on the Mount is not a code of rules to be mechanically followed; it is the description of the life which any man will spontaneously lead when once the Spirit of Christ has taken complete possession of his heart.
