I have no idea, but many whom say the prayer are false converts as evidence of the lack of fruit and a real conversion in their lives. But this is not to say that the sinners prayer is all bad. But in general the LAW and the conviction of sin must be preached first for a true convert to be born. I know this may be hard for you to understand given your Arminianism that you often preach.
Have you never read the story of the ten lepers that Jesus healed? How many came back and thanked him?
Luk 17:11 And it came to pass, as he went to Jerusalem, that he passed through the midst of Samaria and Galilee.
12 And as he entered into a certain village, there met him ten men that were lepers, which stood afar off:
13 And they lifted up their voices, and said, Jesus, Master, have mercy on us.
14 And when he saw them, he said unto them, Go shew yourselves unto the priests. And it came to pass, that, as they went, they were cleansed.
15 And one of them, when he saw that he was healed, turned back, and with a loud voice glorified God,
16 And fell down on his face at his feet, giving him thanks: and he was a Samaritan.
17 And Jesus answering said, Were there not ten cleansed? but where are the nine?
18 There are not found that returned to give glory to God, save this stranger.
19 And he said unto him, Arise, go thy way: thy faith hath made thee whole.
How many of these lepers returned and thanked Jesus?
How many were healed of their leprosy?
Yes, and no. But unlike what many Arminian believe, its not their prayer that saves them, but its God whom does the saving.
Do you believe everything some Calvinist tells you? Do you really believe that non-Cals believe a prayer saves them?
And just how do you tell if a person is living good enough to be saved?
Can a person who drinks and listens to Rock music be saved? Can a man who lives with a woman when they are not married be saved?
Better be careful how you judge folks, you will be judged with the same judgment you judge others.
