When temptation besets us, we experience pain of conscience. A sensitive conscience is the evidence of a healthy spirit. The pain or guilt we feel is the spirit’s reaction to temptation, imperfection, or sin. Conscience is the companion of every traveler (Moro. 7:16–19), it can also make the trip very uncomfortable, since “all have sinned” and “the Lord cannot look upon sin with the least degree of allowance” ( Rom. 3:23 D&C 1:31). Thanks be to God for this supernal gift, for it can lead us to repentance and peace of conscience (Mosiah 4:1–3).
