The last several messages have been around psalms of lament. In those psalms people cry out to God for help in their distress. This psalm answers the question, 'what happens after God hears the lament and helps?'
We respond to God's grace through thanksgiving. This psalm gives us two different ways to offer thanks to God. First we publically tell the story of God's help. Second we give generously to God and the work he is about.
