As the life of a deer depends upon water, so our lives depend upon God. Those who seek him and long to understand him find eternal life. Feeling separated from God, this psalmist wouldn't rest until he restored his relationship with God because he knew that his very life depended on it. Do you thirst for God?
Psalms 42:1
Psa 42-49 were written by the descendants of Korah. Korah was a Levite who led a rebellion against Moses (Num 16:1-35). He was killed, but his descendants remained faithful to God and continued to serve God in the Temple. David appointed men from the clan of Korah to serve as choir leaders (1Ch 6:31-38), and they continued to be Temple musicians for hundreds of years (2Ch 20:18-19).
Psalms 42:4-5
The writer of this psalm was discouraged because he was exiled to a place far from Jerusalem and could not worship in the Temple. During these God-given holidays, the nation was to remember all that God had done for them.
Psalms 42:5-6
Depression is one of the most common emotional ailments. One antidote for depression is to meditate on the record of God's goodness to his people. This will take your mind off the present situation as you focus your thoughts on God's ability to help you rather than on your inability to help yourself. When you feel depressed, take advantage of this psalm's antidepressant: Read the Bible's accounts of God's goodness, and meditate on them.
