Thankfulness is clearly a major theme in this psalm. Specifically the psalmist is thankful for God’s justice and rescue.
One of the first thing the psalmist does is “recount.” How can we be thankful if we don’t remember? It doesn’t matter the day or the circumstances that we find ourselves in, we can always stop and remember the justice and rescue of God. Perhaps, I find myself in a current trial or suffering. Perhaps, I do not yet see God’s rescue. But can I remember and recount a time when God has put an end to wickedness? Can I remember a time that God has lifted me up?
By the time verse 13 the psalmist has moved to a request for rescue. It is as we remember God’s prior faithfulness that we call out for grace for the present season. As he says in verse 18, “For the needy shall not always be forgotten, and the hope of the poor shall not perish forever.”
This is an interesting lesson. The son is told to “save yourself,” but the means by which he saves himself is to plead for mercy. I think that the instruction is not to hide or just hope for the best. Instead, don’t be afraid to make the need for mercy known if you are “snared in the words of your mouth.”
