From Carrie Sandom, speaking on Psalm 40:
There are those who are compromised, consumed, and cold-hearted. And they’re all in a miry bog. And they aren’t the only ones. In a group this size, there are many of us trapped in a miry bog as well. Bogs come in various shapes. We know what it’s like, and many have experienced that the more we struggle to escape, the more bound we become.
But God knows we desire to escape, and in the Psalms, God gives us words to the desperation of our hearts. The Psalms were written supremely to each them about God; who He is and how He relates to His people. But the also taught how to respond to Him, regardless of the situation in which we find ourselves.
