If the conscience is misinformed, then we seek the reasons for this misinformation. Is it misinformed because the person has been negligent in studying the Word of God? God has been pleased to reveal His principles to us, and He requires that each Christian master those principles so that the conscience is informed. I may think that it's fine to indulge in a particular activity that God absolutely prohibits, and I cannot say to God on the last day, "I didn't know that you would be displeased with this form of behavior. My conscience didn't accuse me, and I acted according to my conscience." In such a case you acted according to a conscience that was ignorant of God's Word that was available to you and that you were called to study and be diligent in your understanding thereof.
