The idea of "asking Jesus into your heart" is not helpful. Instead note the preaching of Jesus which was basically "repent for the kingdom is at hand" whilst in the book of Acts Paul states that God commands all men everywhere to repent. Other elements are that Jesus has been made both Lord and Christ. There is no hope except calling out to God. There are no words that can be used except the persons own heartfelt words that he prays. If the Holy Spirit is convicting him then he will find the words to say.

I would also keep in mind two key points:-

1. "No one comes to the Son unless the Father draws him" (Jn 6.44)
2. It is the Holy Spirit's role to convict the world of sin, righteousness and judgement (Jn 16.8)

If neither of these two things happen then despite the best reasoned arguements and the clearest presentation of the gospel, they will never be converted. If one of these two things happens then the other will also occur and as I said above there is no set prayer to pray or pattern of words to use. The convicted person will find the words from his own heart.

I would tend to show that although the person may be good living the heart harbours pride, lust, greed, envy etc. If these are given free reign then wh knows what the person could end up doing.

We should pray that the Father would draw (the actual word implies being even dragged) more to the son. Humanists need to be dragged by the Holy Spirit to the sin just as the good living religious person.
