What will it cost you to follow Jesus? J.C. Ryle writes:
1-True Christianity will cost one 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 really feel as well as say the Prayer Book words, that he has “erred and gone astray like a lost sheep,” that he has “left undone the things he ought to have done, and that there is no health in him.” He must be willing to give up all trust in his own morality, respectability, praying, Bible reading, church–going, and sacrament receiving, and to trust in nothing but Jesus Christ.
2-True Christianity 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. They may struggle hard with him every day and sometimes almost get the mastery over him. But he must never give way to them. He must keep up a perpetual war with his sins. It is written, “Cast away from you all your transgressions.” “Break off thy sins . . . and iniquities.” “Cease to do evil” (Ezek. 18:31; Dan. 4:27; Isa. 1:16).
3-Christianity will cost a man his love of ease. He must take pains and trouble if he means to run a successful race toward heaven. He must daily watch and stand on 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 imagination, 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. In attending to these things, he may come far short of perfection; but there is none of them that he can safely neglect. “The soul of the sluggard desireth, and hath nothing: but the soul of the diligent shall be made fat” (Prov. 13:4).
4-Lastly, true Christianity 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. The Master says, “Remember the word that I said unto you, ‘The servant is not greater than his Lord.’ If they have persecuted Me, they will also persecute you; if they have kept My saying, they will keep yours also” (John 15:20).
I grant it costs much to be a true Christian. But what sane man or woman 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.
