If your conscience is too easily wounded, don't violate it. To violate even a weak conscience is to train yourself to override conviction, and that will lead to overriding true conviction about real sin. Moreover, violating the conscience is a sin in itself (Romans 14:23), bringing legitimate guilt for a real offense against God. So, respond to your conscience, even if it’s weak, and then continue to inform your conscience with God’s Word so it can begin to function with reliable data.
John MacArthur
