Psalm 40 shows us that we can confidently approach God in our time of need, and that we can continue to worship and rejoice in him, even when our circumstances would indicate otherwise. It also sets a clear pattern that God doesn’t always tie things up in a perfect, red bow at the end. It doesn’t promise that “all who want to take my life be put to shame and confusion.” That prayer is prayed, but as far as we know, those attempted murderers are still on the prowl. What it does promise is we can go to God as our refuge and strength in the midst of this.
