You are missing the point. According to OSAS proponents (Not all of them but many of them), they will say that you
don't have to cry out to God to have mercy on their lives. All you need is a "belief" on Jesus and that is it. How you love God and love others plays no factor into the mix of one's right standing with God. The fruits of righteousness do not need to bear fruit in a believer's life according to many (Not all) OSAS proponents. Granted, I do not believe in "Works Salvationism." I believe God does the work in the believer once they have been truly saved and they are abiding in God (Who is the source of their salvation). The majority who voted in my poll here at CC, had expressed their belief that you can be out of fellowship with God and still be saved.

This implies a doctrine of immorality. That God will save a person and take them home to Heaven even when they are being evil up until the point of their deaths. For many here believe that a believer can commit sin, then die, and still be saved. They believe physical death (and not spiritual death) is the result of committing a sin (Like with Ananias and Sapphira). But if God wanted to save Ananais and Sapphira and their hearts were right with God, then why didn't the Lord allow them time to repent? What kind of message does that send when He kills a person for doing evil? Do you really expect me to believe they were saved? I mean, if you seen someone struck down by some super natural means, are you going to think Judgment or salvation? Was their ever a point in the Bible where God did this before? I don't so.
Anyways, I brought up Luke 18:9-14 because what it clearly illustrates is two pictures of a type of believer we can see today.
Picture #1 = Believer who cries out to God to have mercy on him (Which lines up with confessing sin, 1 John 1:9, and the Lord's prayer).
Piciture #2 - False Believer who thinks they are God's righteous child and does not love another.
Picture #1 describes the believer who humbles themselves down before God to have mercy on them and their sins. Their cry out to God is not an excuse for them to continue in sin, but it is a cry to God so as to help them to stop so they can walk in His good ways. This is the true believer today who has a proper understanding on 1 John 1:9. They believe confessing and admitting before God that they need His grace and forgiveness.
Picture #2 describes the false believer who does not need to go to God to be forgiven. He is God's righteous child and he is saved no matter what. But the Pharisee's fruit within his life shows otherwise because he does not love another. He is proud and beats his chest and thinks he is better than the Tax Collector and thanks God for saying he is glad he is not like that Tax Collector.
So we can see that if you were to compare both pictures side by side and try to line them up next to the OSAS proponent who believes they can sin and still be saved versus the believer who believes they have to cry out to God for forgiveness, then we can easily conclude that the OSAS sin and still saved belief is false.
