People who say "the sinner's prayer" of repentance - but make no effort to put it to practice in their lives, are only deceiving themselves! They can't get to heaven that way! People who are deceived into thinking that can get them to heaven, are those who think they can get that wonderful gift of salvation completely for free. Have you ever noticed how quick people are to accept a free gift that they really want? There are some things that everyone wants. And salvation is one of those things. They may not all know about Jesus and the salvation that comes through Him. But no one wants to end up in a place like hell! So in effect, they do all want salvation. But only those who are willing to "pay"(accept Jesus as Lord and Savior of their life) the hugely reduced "cost" (the cost of having perfect righteousness and having never sinned) they must "pay" "(accept Jesus as Lord and Savior of their life) can be saved.
Luke 14:27-28
27 And whosoever doth not bear his cross, and come after me, cannot be my disciple.
28 For which of you, intending to build a tower, sitteth not down first, and counteth the cost, whether he have sufficient to finish it?
KJV
Matt 7:21-23
21 Not every one that saith unto me, Lord, Lord, shall enter into the kingdom of heaven; but he that doeth the will of my Father which is in heaven.
22 Many will say to me in that day, Lord, Lord, have we not prophesied in thy name? and in thy name have cast out devils? and in thy name done many wonderful works?
23 And then will I profess unto them, I never knew you: depart from me, ye that work iniquity.
