Related to camp, where day one focused on repentance and day two on belief, I thought it would be helpful to let Spurgeon weigh in. I was reading his sermon An Appeal To Sinners, in preparation for Sunday’s sermon from Luke 15 this morning and came across the following…
Is there is an infidel here who says he shall be well enough off if he shall die the death of annihilation and shall not live in a future world? Well, my Friend, suppose all men die like dogs, I shall be as well off as you are and I think a little better off, even as to happiness and peace in this world. But if—(and mark you I do not put it so because I doubt it)—if it is true that there is a world to come, I would not like to stand in your place in the next world! If it is so that there is a judgment seat and a Hell—(I put it hypothetically, not because I have a doubt about it, but because you tell me you doubt it though I do not think you really do)—if there is such a place, what will you do then?
Why, even now you shake if a leaf falls in the night. You are terrified if the cholera is in the street. You are alarmed if you are a little sick and you rush to the physician and anyone can impose upon you with his medicines, because you are afraid of death. What will you do in the swellings of Jordan, when death gets hold on you? If a little pain frightens you now, what will you do when your body shall shake and your knees shall knock together before your Maker? What will you do, my Hearer when His burning eyes shall eat into your very soul? What will you do, when amid ten thousand thunders, He shall say, “Depart, depart”?
I cannot tell you what you will do. But I will tell you one thing that you dare not do. That is, you dare not say that I have not as simply as ever I could tried to preach the Gospel to the very chief of sinners. Hear it again— “He that believes on the Lord Jesus Christ shall be saved.” To believe is to trust in Christ—to drop into those blessed arms that can catch the heaviest laden sinner that ever breathed. To believe is to fall flat on the promise—to let Him do all for you until He has quickened you and enabled you to work out what He has before worked in you, “your own salvation.” And even this must be “with fear and trembling.”
The bold part is my emphasis and helpful language to employ when we talk of conversion.
