What do you do with that pesky sin you can’t seem to shake? Go to confession. Pray about it like St. Paul prayed to have the thorn removed from his side. Maybe even the thought came that this is something with which you may have to learn to live.
Or maybe someone else needs prayer. Maybe the only help they will receive is from you. You know their sin, you know what a struggle it is, you know the traps, the triggers, the aftermath, the helplessness. Who better to pray for them than one who suffers similarly? Instead of turning inward with an attitude of “woe is I,” a prayer might be offered in earnest, “Lord, you know I understand how this person struggles. Deliver them please. Set them free. Give the courage, strength, and fortitude that they need to be a better version of themselves for you.”
The problem with sin is that it is a radical turning inward; what I want, what I need. Prayer can turn into the same thing. Some of the prayer is great. But if prayer becomes so focussed on the self; my pain, my regret, my cry for mercy, my wanting help to get over this desire; then it does not fully embrace the cure which is to turn outside of oneself, to radically turn outward in love, devotion, attention, and assistance.
We are a Church of sinners. But do we also want to be a Church of people turned in on themselves and concerned about their own problems? Or would we rather be a Church that as a community tries to help each other dig ourselves out of our sins?
