… In the Book of Mormon we read that ‘despair cometh because of iniquity.’ (Moro. 10:22.) ‘When I do good I feel good, ’ said Abraham Lincoln, ‘and when I do bad I feel bad.’ Sin pulls a man down into despondency and despair. While a man may take some temporary pleasure in sin, the end result is unhappiness. ‘Wickedness never was happiness.’ (Al. 41:10.) Sin creates disharmony with God and is depressing to the spirit. Therefore, a man would do well to examine himself to see that he is in harmony with all of God’s laws. Every law kept brings a particular blessing. Every law broken brings a particular blight. Those who are heavy laden with despair should come unto the Lord, for his yoke is easy and his burden is light. (See Matt. 11:28–30.)
