What does Psalm 27:4 mean?

David's top priority in life was his relationship with the Lord. Although he was in the wilderness seeking refuge from his enemies, David's heart was in the tabernacle seeking the beauty of God. He longed to return to the tabernacle and spend the rest of his life in worship. Sometimes trouble drives us closer to the Lord and makes us more desirous of worshiping Him in the fellowship of other believers.

The prophet Jonah realized that when he was in the belly of the great fish his life was fainting away. And yet, he remembered the Lord and prayed to Him (Jonah 2:7). The Lord answered Jonah's prayer and delivered him from the great fish, depositing him safely on shore (Jonah 2:10). The believers to whom the book of Hebrews was addressed were tempted to faint under persecution. So the writer exhorted them to cling to faith "without wavering" and to "stir up one another to love and good works, not neglecting, as is the habit of some, but encouraging one another" (Hebrews 10:23–25).
