All men, by nature, do moral acts. (Rom 2:14-16). However, all men sin (Rom 3:23). No unregenerate man can do enough to earn salvation. One sin is sufficient for condemnation.
So, while it may please God that the unregenerate do moral acts, it is insufficient to stand righteous before Him.
why ?
before you answer , why doesn't God just look at the GOOD WORKS not the sins ?
You know if men can do good works that are acceptable to God , then it shouldn't be too difficult for them to TOTALLY please God .... hey ?
Unregenerate moral actions are indications of knowledge of the law of their conscience. It is by these moral actions, which indicate knowledge of the law, that their immoral actions are judged, and they are condemned.
why ?
I don't get why a man who does works accptable to God would be excluded just because of FEW unacceptable works ... I don't condemn my children for a few mistakes , especially when they are doing stuff which is praisworthy .
neither do I tell them you have to start all over again by being born a second time .... if they do a few mistakes (sins) I say "just improve" , and "don't let it happen again" ... I don't need to start all over again by declaring them in need of salvation by me !
If men can do stuff acceptable to God , then logically it must be that they could always do stuff acceptable to God and would not need a saviour , their good works would cover it !
In any case , I stand with the Reformers and others (taking their understanding from scripture) who decare all man's works are corrupted by sin , and that none of man's works are pleasing or acceptable to God , for every single work of man is either for the Glory Of God and is done BY FAITH or it is not .
According to scripture faith alone is able to make us acceptable to God and "good works" are just like filthy rags to HIM who sees all things clearly , who sees the very motives and desires of the heart > Jesus certainly preached against the fallacy of outwardly keeping God's Law as a certain wide road to destruction , Christ Himself directly undermined popular thinking about man and "good- works" ... "Good master " says one , Christ replies "Only God is good" ......
the Gospel of Matthew (5) tells us about man's goodness and thinking he is pleasing God by outwardly Law keeping ..... it's condemned because man is a condemned creature in need of TOTAL regeneration JUSTIFICATION and Salvation.
