David repeats this refrain over and over. He says his soul thirsts for God (verse 2) like a deer longs for water (verse 1). He acknowledges that he is in mourning (verse 9) and that:
"Deep calls unto deep at the noise of Your waterfalls. All Your waves and billows have gone over me." (Psalm 42:7, NKJV)
It is almost too much for him to bear. There is also the example of Elijah the prophet. God through Elijah had a monumental victory over the 450 pagan priests of Baal at Mt. Carmel (1Kings 19). All the false prophets were killed and Israel's heart turned back to worshipping the true God. Jezebel, the wife of King Ahab, heard what happened and sent word to Elijah that she would make sure he would be dead within a day. When he heard the threat, even after the awesome miracle of Carmel, Elijah decided to run for his life! Traveling to Mt. Horeb he laments to God:
"But he himself (Elijah) went a day’s journey into the wilderness, and came and sat down under a broom tree. And he prayed that he might DIE, and said, 'It is enough! Now, Lord, take my life, for I am no better than my fathers!' " (1Kings 19:4)
Elijah also laments that he is the only prophet of God left alive. God's "cure" was to get him busy again doing His will. He was also told that he was NOT the only righteous man left in Israel! There is also the well-known case of Judas Iscariot. After betraying Jesus to those who hated him he had a dramatic change of heart. His depressed state and remorse was so severe that it drove him to commit the ultimate expression of self-hate.
"When morning came, all the chief priests and elders of the people plotted against Jesus to put Him to death . . .
"Then Judas, His betrayer, seeing that He (Jesus) had been condemned, was remorseful and brought back the thirty pieces of silver to the chief priests and elders, saying, 'I have sinned by betraying innocent blood.' And they said, 'What is that to us? You see to it!' Then he threw down the pieces of silver in the temple and departed, and went and hanged himself." (Matthew 27:1, 3-5)
Many psychologists believe that one of the causes of depression is negative, pessimistic thinking which creates low self-esteem. They have known for some time that negative, irrational self-talk in the form of simple declarative sentences often leads to this state of mind. Therefore, appropriate self-talk can lift us out of it.
