Is there anyone else here in this room who wants to accept Jesus as Lord and Savior? Thank you I see that hand, you may put them down. Is there any one else? How about the others? Thank you, you may put your hand down. Is there any one else?
In Acts when people get agitated with their sins, they cry out "what must I do to be saved" - Paul would reply "believe in the Lord Jesus Christ and you will be saved with your household". It does not say there that they prayed the sinner's prayer, rather they got baptized.
