Now here is a Scripture that could get confusing.

 

John 9:31(NKJV)

Now we know that God does not hear sinners; but if anyone is a worshiper of God and does His will, He hears him. 

Here again is an example of why the study of Scripture has to be taken in its entirety and why it takes the discernment of the Holy Spirit.

The first part, God does not hear sinners.  OK, that makes sense…except then how is it we are saved when we accept Jesus if God doesn't hear us? 

Now look at the second part.  God hears those who are doing His will.  OK, again that makes sense…except that Paul tells us we are all sinners who fall short of the glory of God even when we follow God and attempt to do His will. 

But if we are all sinners, even when we try to do God's will, then aren't we back to God not hearing us? 

I think the differentiation here is one of the heart.  As I have pointed out before, Jesus is concerned about where our heart is.  I think "sinners" in the first part is referring to those who have rejected God.  Those whose hearts are really on God and following God, while still sinners in the sense that Paul was talking about are not sinners in the sense that the first part of this Scripture is talking about.  Make sense?
