Romans 14:23 King James Version
23 And he that doubteth is damned if he eat, because he eateth not of faith: for whatsoever is not of faith is sin.
Can it be taken from Romans 14:23 that everything an unsaved person does is sin, or is this not something that can be taken from Romans 14:23?
It is the tree of the knowledge of good and evil, so a person in the world can do good.
But although the world can do good their motivation would be of the flesh, which in the flesh dwells no good thing.
Which they would want people to think they are special, and exalt themselves because of that, not giving glory to God.
Which a man called Jesus good, and He said why call me good for there is only one that is good, and that is God, which the man Christ Jesus gave glory to God that the only reason He did good was because God caused Him to do good.
Which we can do good, but truly being good is being led of the Spirit, and we are not good with sin in our life.
The world will fall short of that good and a little leaven leavens the whole lump.
We can do good in the world but the motivation is flesh which the world wants to exalt themselves, but they have sin for they cannot overcome the flesh, where a person led of the Spirit will exalt God for them doing good, and they can overcome the flesh.
So the good we do in the world does not qualify as the goodness of God although it can help people in that goodness, and would want to stay away from some sins, for the world chooses what sins they like and do not like.
