When I kept it all inside, my bones turned to powder, my words became daylong groans. The pressure never let up; all the juices of my life dried up. Then I let it all out; I said, "I’ll make a clean breast of my failures to God." Suddenly the pressure was gone— my guilt dissolved, my sin disappeared. Psalm 32:3-5 (TM)
I’ve always thought that we Protestants threw some babies out with the bathwater when Martin Luther nailed his grievances with the Catholic church on the Wittenburg door back in 1517. One of them is confession. Sure, I don’t think I need a human priest to absolve us (David took his sin right to God, and look at the result) – but I do think that we need confession. It is good for the soul.
I’m blessed with friends and loved ones with whom I can admit my failures, and I know from them I will receive forgiveness and grace. I also have God’s promise that when I confess my sin, He is faithful and just and will forgive my sin and "purify me from all unrighteousness."
