The sinners prayer will do man good as a $7.00 bill in Wal-mart as it does not exist. All sin is of the devil period.
Galations 2: 17] But if, while we seek to be justified by Christ, we ourselves also are found sinners, is therefore Christ the minister of sin? God forbid.
 For if I build again the things which I destroyed, I make myself a transgressor.
 For I through the law am dead to the law, that I might live unto God.
 I am crucified with Christ: nevertheless I live; yet not I, but Christ liveth in me: and the life which I now live in the flesh I live by the faith of the Son of God, who loved me, and gave himself for me.
 I do not frustrate the grace of God: for if righteousness come by the law, then Christ is dead in vain.
1st John 3:  Whosoever committeth sin transgresseth also the law: for sin is the transgression of the law.
 And ye know that he was manifested to take away our sins; and in him is no sin.
 Whosoever abideth in him sinneth not: whosoever sinneth hath not seen him, neither known him.
 Little children, let no man deceive you: he that doeth righteousness is righteous, even as he is righteous.
 He that committeth sin is of the devil; for the devil sinneth from the beginning. For this purpose the Son of God was manifested, that he might destroy the works of the devil.
 Whosoever is born of God doth not commit sin; for his seed remaineth in him: and he cannot sin, because he is born of God.
