Let the wicked forsake his way, and the unrighteous man his thoughts… – Isaiah 55:7

“Let the wicked forsake his way.” It does not say, “Let him own that his way is bad.” There are some who will say, ‘Oh, yes, I know that my way is very wrong;” and there they stop. Such an admission as that will not save you, my friend; you must forsake your way as well as own that it is wrong. To know that it is wrong, and yet to go on in it, will double your sin. This kind of confession will not help you in the least; on the contrary, it will only increase your guilt. You must forsake your wicked way if you are to be forgiven. “Oh, sir,” you say, “I am very sorry for all the sin that I have committed!” I am glad that you are, and I hope that you will be still more so; but that sorrow alone will never save you. It is not saying, “I am sorry,” nor yet your being sorry for your sin that will save you; that is right as far as it goes, but you must forsake the sin as well as be sorry for it. “I must forsake it; well, I resolve that I will do so.” Yet that resolve by itself will not save you, for there are plenty of good resolutions that are good for nothing. You have actually to forsake your wicked way before you have complied with the requirements of our text. I know how the devil will try to deceive you, when you have made a good resolution. He will say, “Ah, you are a fine fellow; and that is a splendid resolution of yours!” Yet mere resolutions are not worth a penny a thousand; we must act, not simply resolve what we mean to do. We must not be like the man who owes a lot of money, and has not a penny to pay, yet who keeps on saying to his creditors, “I hope I shall be able to pay you tomorrow.” Then, when that day comes, he says he is very sorry, but he missed the friend he expected to see, so he must postpone the payment for a few days; yet, when the few days have passed, there is still nothing forthcoming. So it is with many who resolve to forsake sin; they are like those who promise, but never pay. This will not do; you must forsake your sin if it is to be forgiven.~ C.H. Spurgeon
