J.C. Ryle writes in his classic work Holiness that there are four things a person must be ready to give up if they wish to become a Christian.
#1: Counting the Cost: Your Self-Righteousness
#2: Counting the Cost: Your Sins
#3: Counting the Cost: Your Love of Ease
#4: Counting the Cost: The Favor of the World
Summary: Contemplating the Four Costs
[Before going through the four points] Let there be no mistake about my meaning. I am not examining what it costs to save a Christian’s soul. I know well that it costs nothing less that the blood of the Son of God to provide atonement, and to redeem man from hell. The price paid for our redemption was nothing less than the death of Jesus Christ on Calvary. The point I want to consider is another one altogether. It is what a man must be ready to give up if he wishes to be saved. It is the amount of sacrifice a man must submit to if he intends to serve Christ. It is in this sense that I raise the question, ‘What does it cost?’ And I believe firmly it is a most important one.”
What does it cost to be a true Christian?
1) It will cost him his self-righteousness. He must cast away all pride and high thoughts, and conceit of his own goodness. He must be content to go to heaven as a poor sinner saved only by free grace, and owing all to the merit and righteousness of another. He must be willing to give up all trust in his own morality, respectability, praying, Bible-reading, Church-going, and sacrament-receiving, and trust in nothing but Jesus Christ. Let us set down this item first and foremost in our account. To be a true Christian it will cost a man his self-righteousness.
2) It will cost a man his sins. He must be willing to give up every habit and practice which is wrong in God’s sight. He must set his face against it, quarrel with it, break off from it, fight with it, crucify it, and labor to keep it under, whatever the world around him may say or think. He must do this honestly and fairly. There must be no separate truce with any special sin which he loves. He must count all sins as his deadly enemies, and hate every false way. Whether little or great, whether open or secret, all his sins must be thoroughly renounced. Let us set down that item second in our account. To be a Christian it will cost a man his sins.
3) It will cost a man his love of ease. He must take pains and trouble, if he means to run a successful face towards heaven. He must daily watch and stand his guard, like a soldier on enemy’s ground. He must take heed to his behavior every hour of the day, in every company, and in every place, in public as well as in private, among strangers as well as at home. He must be careful over his time, his tongue, his temper, his thoughts, his imaginations, his motives, his conduct in every relation of life. He must be diligent about his prayers, his Bible-reading, and his use of Sundays, with all their means of grace. “This also sounds hard. There is nothing we naturally dislike so much as ‘trouble’ about our religion. We hate trouble. We secretly wish we could have a ‘vicarious’ Christianity, and could be good by proxy, and have everything done for us. Anything that requires exertion and labor is entirely against the grain of our hearts. But the soul can have ‘no gains without pains.’ Let us set down that item third in our account. To be a Christian it will cost a man his love of ease.
4) It will cost a man the favor of the world. He must be content to be thought ill of by man if he pleases God. He must count it no strange thing to be mocked, ridiculed, slandered, persecuted, and even hated. He must not be surprised to find his opinions and practices in religion despised and held up to scorn. He must submit to be thought by many a fool, an enthusiast, and a fanatic – to have his words perverted and his actions misrepresented. In fact, he must not marvel if some call him mad. “I dare say this also sounds hard. We naturally dislike unjust dealing and false charges, and think it very hard to be accused without cause. We should not be flesh and blood if we did not wish to have the good opinion of our neighbors. It is always unpleasant to be spoken against, and forsaken, and lied about, and to stand alone. But there is no help for it. The cup which our Master drank must be drunk by His disciples. They must be ‘despised and rejected of men’ (Isaiah 53:3). Let us set down that item last in our account. To be a Christian it will cost a man the favor of the world.
Bold indeed must that man be who would dare to say that we may keep our self-righteousness, our sins, our laziness, and our love of the world, and yet be saved? I grant it costs much to be a true Christian. But who in his sound senses can doubt that it is worth any cost to have the soul saved? When the ship is in danger of sinking, the crew think nothing of casting overboard the precious cargo. When a limb is mortified, a man will submit to any severe operation, and even to amputation, to save life. Surely a Christian should be willing to give up anything which stands between him and heaven. A religion that costs nothing is worth nothing! A cheap Christianity, without a cross, will prove in the end a useless Christianity, without a crown.
