I attended a Bible college that taught much of what non-Lordshippers teach. One of the things they taught in evangelism classes was that if we were witnessing to somebody, and they started talking about sin that they would have to give up if they became a Christian, that we were to tell them that they didn't have to change anything as a Christian. In fact, we were encouraged to tell them that they would never have to set foot inside a church, crack open a Bible, or anything after Salvation. All they had to do was pray the prayer. All they had to do was "ask Jesus to save them and really mean it."
Now the other day, I was witnessing to a young man about my age that I work with. I was asking him questions concerning religion, and he got uncomfortable and defensive after a few minutes of talking. Finally he said "I can't become a Christian." I inquired of him "why not?" He responded saying "If I become a Christian, then I can't go out and get drunk every weekend. I can't sleep with my girlfriend, I can't smoke my cigarettes, I can't do any of the stuff that I like to do. I LIKE MY SIN TOO MUCH TO GET SAVED." He realized, as an unregenerate man, that salvation meant obedience to Christ, and leaving his sin behind. And he didn't like that. Several times I've been witnessing to people, and they've asked questions like "If I get saved, do I need to go to church? Do I need to stop getting drunk? Do I need to stop sleeping around?"
If you were in a situation like I described above, how would you respond to that young man? How would you respond to somebody who asked if they would have to give something up as a result of Salvation? How would you advise someone who didn't want to get saved because it would mean leaving their sin behind?
