I think the problem was, and still is with some churches, is that the focus is on what we do, have we made Him the Lord of our life, have we accepted Him as our Savior, have we made a decisiion for Christ, have we asked Him to come into our hearts or into our lives, instead of on what Jesus did to save us. Realize the Bible says in 1 Corinthians 12 "that no one can say Jesus is Lord but by the Holy Spirit" so unless the Holy Spirit gives us conviction in our hearts that we are sinners who need a Savior in the first place, we cannot make a decision for Christ. I was not raised in any church so I had no idea, for example, that it is a sin to have sex with someone while not being married, fornicatiion, as I thought it was OK as long as I was in Love. I had some concept of stealing being wrong, etc, but I had no idea that without a Savior that candy bar I may have stolen when I was 11 years old was enough to keep me out of heaven if it depended on my performance, my works as, from James 2, if we stumble at one point in the law we are guilty of the whole law. I was not really a bad kid overall so it took the Holy Spirit pointing out things I have done over the years would have kept me out of heaven if it despended on what I do to show me I am a sinner. Thank God I found that out and that Jesus died for all of those sins to take them away so that God sees them no more so I will go to heaven. Faith comes from hearing the word, from Romans 10, so people need to hear specfically that Jesus died for our sins and rose again on the third day, which is the gospel, there is no other gospel and, again, we can't assume people have heard what it is. That is the best thing about the church I attend that they focus on the cross at all times above everything else.
