As a Christian, you have the capacity to walk before God with a clear conscience:
1. Confess and forsake known sin. Examine your guilt feelings in light of Scripture. Deal with the sin God’s Word reveals (Pr. 28:13; 1 Jn. 1:9; Jas. 5:16; Psm. 32:5).
2. Ask forgiveness and be reconciled to anyone you have wronged (Mt. 5:23-24; 6:14-15).
3. Make restitution to those you’ve wronged (Num. 5:6-7; Lk. 19:8; Phile. 19).
4. Don’t procrastinate in clearing your wounded conscience. Some people put off dealing with their guilt, thinking their conscience will clear itself in time. It won't. Procrastination allows the guilt feelings to fester. That in turn generates depression, anxiety, and other emotional problems (Ac. 24:16).
5. Educate your conscience. A weak, easily grieved conscience results from a lack of spiritual knowledge (1 Cor. 8:7).
