In this sermon The Sinner's Prayer, no one in the Bible ever prayed for their initial salvation. They did however believe, repent, confess Jesus and be immersed in water for the forgiveness of their sins. The sinners prayer is an innovation that thwarts God's plan of salvation. First they replaced believers baptism by immersion with infant baptism by sprinkling. Second they later replaced baptism altogether with the "sinners prayer" so that baptism is no longer even part of the plan of salvation. If you prayed the "sinners prayer" for your salvation, you really need to study the following and ask your pastor if this is true? He will know all the details I am sure.
