Here are some Protestant voices on the ‘sinner’s prayer’:
Charles Spurgeon (a Baptist):
Quote:
"Sometimes we are inclined to think that a very great portion of modern revivalism has been more a curse than a blessing, because it has led thousands to a kind of peace before they have known their misery; restoring the prodigal to the Father’s house, and never making him say, ‘Father, I have sinned.’ How can he be healed who is not sick? or he be satisfied with the bread of life who is not hungry? The old-fashioned sense of sin is despised, and consequently a religion is run up before the foundations are dug out. Everything in this age is shallow. Deep-sea fishing is almost an extinct business so far as men’s souls are concerned. The consequence is that men leap into religion, and then leap out again. Unhumbled they come to the church, unhumbled they remained in it, and unhumbled they go from it.
David Martin Lloyd-Jones (a Presbyterian):
Quote:
"Most would agree with my sixth point which is that this method tends to produce a superficial conviction of sin, if any at all. People often respond because they have the impression that by doing so they will receive certain benefits. . . .
"Or take another illustration out of my own experience. In the church where I ministered in South Wales I used to stand at the main door of the church at the close of the service on Sunday night, and shake hands with people as they went out. The incident to which I am referring concerns a man who used to come to our service every Sunday night. He was a tradesman but also a heavy drinker. He got drunk regularly every Saturday night, but he was also regularly seated in the gallery of our church every Sunday night. On the particular night to which I am referring I happened to notice while preaching that this man was obviously being affected. I could see that he was weeping copiously, and I was anxious to know what was happening to him. At the end of the service I went and stood at the door. After a while I saw this man coming, and immediately I was in a real mental conflict. Should I, in view of what I had seen, say a word to him and ask him to make his decision that night, or should I not? Would I be interfering with the work of the Spirit if I did so? Hurriedly I decided that I would not ask him to stay behind, so I just greeted him as usual and he went out. His face revealed that he had been crying copiously, an he could scarcely look at me. The following evening I was walking to the prayer-meeting in the church, and, going over a railway bridge, I saw this same man coming to meet me. He came across the road to me and said, ‘You know, doctor, if you had asked me to stay behind last night I would have done so.’ ‘Well,’ I said, ‘I am asking you now, come with me now.’ ‘Oh no,’ he replied, ‘but if you had asked me last night I would have done so.’ ‘My dear friend,’ I said, ‘if what happened to you last night does not last for twenty-four hours I am not interested in it. If you are not as ready to come with me now as you were last night you have not got the right, the true thing. Whatever affected you last night was only temporary and passing, you still do not see your real need of Christ.’
Are they more informed and righteous than the Catholics here ?
