The Spirit convicts people of their sins. What is sin? Breaking God's Laws. Is not sinning breaking one or many of those ten?
I was hoping Evan would reply. The post was to him. So often on the BB he has avoided my requests for Scriptural basis for his view on evangelism.
My caveat to your answer: this is all true, but the thread is specifically about using the Decalogue in evangelism, and Evan, the OP author, says this is the "preferred method" of evangelism. That is what I am disagreeing with.
Now, if a heathen person like a citizen of Athens (to Paul) or modern Japan (to me) hears of the Decalogue, they will know nothing about it and even be confused. However, they do have the law in their hearts, namely their conscience (Rom. 2:14-15). If it is already there, and the Holy Spirit will convict them of that, why would I think it was my job to fling the Decalogue at them?
Before going to Japan I read a book that said it was a "shame society" and they did not think about sin. That was mistaken. The problem was how things are worded. The typical word for sin is
tsumi, but that also means crime and they will say they have not sinned. However, if you use the term
warui (bad) they immediately understand, and say that yes, they have done bad things. So, if they have the law in their hearts, why do I have to quote it to them?
