7 Bible Verses About "Good Works" of Non-Christians Being Sin (ESV)

23 But whoever has doubts is condemned if he eats, because the eating is not from faith. For whatever does not proceed from faith is sin.

6 And without faith it is impossible to please him, for whoever would draw near to God must believe that he exists and that he rewards those who seek him.

8   The sacrifice of the wicked is an abomination to the LORD,
    but the prayer of the upright is acceptable to him.

9   If one turns away his ear from hearing the law,
    even his prayer is an abomination.

27   The sacrifice of the wicked is an abomination;
    how much more when he brings it with evil intent.

6   We have all become like one who is unclean,
    and all our righteous deeds are like a polluted garment.
  We all fade like a leaf,
    and our iniquities, like the wind, take us away.

9   The way of the wicked is an abomination to the LORD,
    but he loves him who pursues righteousness.
