“...if you want to be saved, you must accept a prepared salvation, on already prepared and full and present. You must be wiling to give up al your sins and be saved from them—now and forever. Until you agree to this, you cannot be save at all. Many people would be willing to be saved in heave, if they could hold on to some sins while on earth—or rather they think they would like heaven on such terms. But the fact is, they would dislike a pure heart and a holy life in heaven as much as they do on earth, and they utterly deceive themselves in supposing that they are ready or even willing to go to the heaven that God has prepared for His people. No, there can be no heaven except for those who accept a salvation from all sin in this wold. They must take the Gospel as a system that hold no compromise with sin—a system that intends full deliverance from sin even now, and makes provisions accordingly. Any other gospel is not the true one, and to accept Christ's Gospel in any other sense is not to accept it at all. Its first and its last condition is sworn and eternal renunciation of all sin.—Charles Finney, God's Call, pages 170-171
