Psalm 40: 1-10 is a great scripture. It describes how we go from being stuck in a "miry bog" (life) all the way to preaching to the "great congregation". I believe this is about our Journey of Faith and that we need to grow into the unique "call to ministry" that God has for each of us.
Since I recorded this as a message I gave at Lake Cities United Methodist Church I have now converted BACK to The One, Holy, Catholic and Apostolic Church with proper Church Authority in the Roman Catholic Church.
I encourage all to look into the Catholic Church - it has all the Truth you and society needs and all the Graces of God are available to you through the Mass, the Eucharist and all the other Sacraments. It is SO GOOD to be Catholic! Praise God!
