22The faith that you have, keep between yourself and God. Blessed is the one who has no reason to pass judgment on himself for what he approves. 23But whoever has doubts is condemned if he eats, because the eating is not from faith. For whatever does not proceed from faith is sin.
Do you have reason to pass judgment on yourself for the things you do and approve of others doing?
Blessed is the one who has no reason to do so.
Have faith in the things you do. If you have reasons and convictions for doing or not doing something which falls into the realm of Christian freedom, abide by them. You will be blessed if you do so.
If you do not have faith or do the thing against which you have faith because you doubt like a wave tossed to and fro, the thing you do condemns you and your conscience.
Con - with, Science - knowledge.
If you go against the things you know or believe you know, the thing you do does not proceed from faith, but from doubt. Paul states here this is sin.
Have faith in God. Not in your decisions or positions. Faith in God. That is goal.
