All of us desire to have as much happiness as this life can afford. But only a comparatively few people are really happy. Why are so many people unhappy? The great burden of unhappiness which mankind is struggling with is traceable to the fact that only a comparatively few people are familiar with the source of true happiness. 

Pleasure is not the source of happiness. Dr. Viktor E. Frankl, president of the Austrian Medical School of Psychotherapy, and professor of psychiatry and neurology at the University of Vienna, said: “When we set up pleasures as the whole meaning of life, we insure that in the final analysis life shall inevitably seem meaningless.” (The National Observer, July 12, 1965, p. 22)
 Money is not the source of happiness. King Solomon, the son of David, said, “He that loveth silver shall not be satisfied with silver; nor he that loveth abundance with increase: this is also vanity.” (Ecclesiastes 5.10) 

The source of happiness is the peace of mind, and the source of peace is a clean conscience, which is the result of obedience to the commandments of God. 

Isaiah, the prince of the prophets, wrote, “And the work of righteousness shall be peace; and the effect of righteousness quietness and assurance for ever.” (Isaiah 32.17) He also wrote, “But the wicked are like the troubled sea, when it cannot rest, whose waters cast up mire and dirt. There is no peace, saith my God, to the wicked.” (Isaiah 57.20-21) 

The apostle Peter wrote, “For he that will love life, and see good days, let him refrain his tongue from evil, and his lips that they speak no guile: let him eschew evil, and do good; let him seek peace, and ensue it. For the eyes of the Lord are over the righteous, and his ears are open unto their prayers: but the face of the Lord is against them that do evil.” (1 Peter 3.10-12)
