Conscience

that faculty of the mind, or inborn sense of right and wrong, by which we judge of the moral character of human conduct

It is common to all men. Like all our other faculties, it has been perverted by the Fall (John 16:2; Acts 26:9; Rom. 2:15).

It is spoken of as "defiled" (Titus 1:15), and "seared" (1 Tim. 4:2).

A "conscience void of offense" is to be sought and cultivated (Acts 24:16; Rom. 9:1; 2 Cor. 1:12; 1 Tim. 1:5, 19; 1 Pet. 3:21).
