"But showed first to them of Damascus, and at Jerusalem, and throughout all the coasts of Judea, and then to the Gentiles, that they should repent and turn to God, and do works meet for repentance." Acts 26:20
The Problem with Modern Evangelism. Many Christians obtain “decisions” by using the following method: “Do you know that you are going to heaven when you die?” Most will say, “I hope so.” The Christian then says, “You can know so. The Bible says ‘All have sinned.’ Jesus died on the cross for our sins, and if you give your heart to Him today, you can know for sure that you are going to heaven. Would you like to have that assurance that you will go to heaven when you die?” He will almost always say, “Yes.” The person is then led in what is commonly called a “sinner’s prayer.” (Click here for why the sinner's prayer is unbiblical.)
There are a few difficulties with the popular approach: 1) There is no mention of Judgment Day—the very reason men are commanded to repent; 2) There is no mention of hell; and 3) The Law isn't used to bring the knowledge of sin. The apostle Paul said that the Law was the only means by which he came to know what sin was (Romans 7:7). The modern approach may get a decision or gain a church member, but if there is no biblical repentance, there will be a false conversion and there will be no rejoicing in heaven.
