David faced a lot of troubles in his life. He was beset with personal sin. He was hounded by enemies. He experienced turmoil in his family. He wrote in Psalm 40:4-5, “Blessed is that man that maketh the Lord his trust, and respecteth not the proud, nor such as turn aside to lies. Many, O Lord my God, are thy wonderful works which thou hast done, and thy thoughts which are to us-ward: they cannot be reckoned up in order unto thee: if I would declare and speak of them, they are more than can be numbered.”
The message of Psalm 40 is that even when God answers prayer and provides relief (vv. 1-10), there will usually come a new crisis that forces a return to God as one’s refuge (vv. 11-17).
Indeed, like David, “I need Thee every hour, most gracious Lord … I need Thee, O I need Thee; every hour I need Thee! O bless me now, my Savior; I come to Thee!”
