Romans 14:22-23, Whatsoever Is Not of Faith Is Sin
Whatever in the Christian’s life that “does not spring from faith,” that is, “is not in harmony with an inner conviction that what he is doing is in line with his Christian faith,” this person is sinning because he is trying to silence the voice of conscience…To be sure, a person’s conscience is not the Final Judge of his actions…that Final Judge is God, or if one prefers, the Word of God. [Hendriksen]
