Since some have abused the sinners prayer, some churches disbanded the prayer altogether. The issue is not with methodology but in explanation. We must explain what we mean about the gospel, the prayer, and discipleship.
Not only should we develop a deeper theology of prayer, but also of evangelism. Every believer is responsible to share the gospel message with others. Leave the results to God and preach the gospel.
