Love as A Decision
C.S. Lewis on Love, from Mere Christianity
The rule for all of us is perfectly simple. Do not waste time bothering whether you “love” your neighbour, act as if you did. As soon as we do this we find one of the great secrets. When you are behaving as if you loved someone, you will presently come to love him. If you injure someone you dislike, you will find yourself disliking him more. If you do him a good turn, you will find yourself disliking him less. There is, indeed, one exception. If you do him a good turn, not to please God and obey the law of charity, but to show him what a fine forgiving chap you are, and to put him in your debt, and then sit down and wait for his “gratitude,” you will probably be disappointed. (People are not fools: they have a very quick eye for anything like showing off, or patronage.) But whenever we do good to another self, just because it is a self, made (like us) by God, and desiring its own happiness as we desire ours, we shall have learned to live it a little more or, at least, to dislike it less.
Consequently, though Christian charity sounds a very cold thing to people whose heard are full of sentimentality, and though it is quite distinct from affection, yet it leads to affection. The difference between a Christian and a worldly man is not that the worldly man has only affections or “likings” and the Christian has only “charity.” The worldly man treats certain people kindly because he “likes” them: the Christian, trying to treat everyone kindly, finds himself liking more and more people as he goes on—including people he could not even have imagined himself liking at the beginning.
Good and evil both increase at compound interest. That is why the little decisions you and I make every day are of such infinite importance. The smallest good at today is the capture of a strategic point from which, a few months later, you may be able to go on to victories you never dreamed of. An apparently trivial indulgence in lust or anger today is the loss of a ridge or railway line or bridgehead from which the enemy may launch an attack otherwise impossible.
On the whole, God’s love for us is a much safer subject to think about than our love for Him. Nobody can always have devout feelings: and even if we could, feelings are not what God principally cares about. Christian Love, either towards God or towards man, is an affair of the will. If we are trying to do His will we are obeying the commandment “Thou shalt love the Lord thy God.” He will give us feelings of love if He pleases. We cannot create them for ourselves, and we must not demand them as a right. But the great thing to remember is that, though our feelings come and go, His love for us does not. It is not wearied by our sins, or our indifference, and, therefore, it is quite relentless in its determination that we shall be cured of those sins, at whatever cost to us, at whatever cost to Him.
