The Christian way is different: harder, and easier. Christ says “Give me All. I don’t want so much of your time and so much of your money and so much of your work: I want You. I have not come to torment your natural self, but to kill it. No half-measures are any good. I don’t want to cut off a branch here and a branch there, I want to have the whole tree down. I don’t want to drill the tooth, or crown it, or stop it, but to have it out. Hand over the whole natural self, all the desires which you think innocent as well as the ones you think wicked—the whole outfit. I will give you a new self instead. In fact, I will give you Myself: my own will shall become yours.”
Both harder and easier than what we are all trying to do. You have noticed, I expect, that Christ Himself sometimes describes the Christian way as very hard, sometimes as very easy. He says, “Take up your Cross”—in other words, it is like going to be beaten to death in a concentration camp. Next minute he says, “My yoke is easy and my burden light.” He means both. And one can just see why both are true.
Teachers will tell you that the laziest boy in the class is the one who works hardest in the end. They mean this. If you give two boys, say, a proposition in geometry to do, the one who is prepared to take trouble will try to understand it. The lazy boy will try to learn it by heart because, for the moment, that needs less effort. But six months later, when they are preparing for an exam, that lazy boy is doing hours and hours of miserable drudgery over things the other boy understands, and positively enjoys, in a few minutes. Laziness means more work in the long run. Or look at it this way. In a battle, or in mountain climbing, there is often one thing which it takes a lot of pluck to do; but it is also, in the long run, the safest thing to do. If you funk it, you will find yourself, hours later, in far worse danger. The cowardly thing is also the most dangerous thing.
It is like that here. The terrible thing, the almost impossible thing, is to hand over your whole self—all your wishes and precautions—to Christ. But it is far easier than what we are all trying to do instead. For what we are trying to do is to remain what we call ‘ourselves’, to keep personal happiness as our great aim in life, and yet at the same time be ‘good’. We are all trying to let our mind and heart go their own way—centred on money or pleasure or ambition—and hoping, in spite of this, to behave honestly and chastely and humbly. And that is exactly what Christ warned us you could not do. As He said, a thistle cannot produce figs. If I am a field that contains nothing but grass-seed, I cannot produce wheat. Cutting the grass may keep it short: but I shall still produce grass and no wheat. If I want to produce wheat, the change must go deeper than the surface. I must be ploughed up and re-sown.
