What does the Bible say about spiritual depression?

Spiritual depression, as exemplified in Psalm 42, is a profound sense of despair experienced by believers when they feel distant from God. David, a man after God's own heart, illustrates this struggle by longing for God's presence while being separated from the worshiping community. He does not lose his relationship with God but experiences a loss of the sense of His closeness, highlighting that even the most faithful can face profound trials. This psalm serves as a reminder that a longing for God is essential, as it signifies true spiritual life.
