Against Bitterness

Lord, that there should be any bitterness in my heart, after all you've done for me and given to me, is a wonder and a shame. But there is, from time to time. I confess it. It rises up at odd moments, unexpectedly. I don't want it. I reject it. Let all bitterness and wrath and anger and clamor and slander be put away from me, along with all malice. By your mercy and grace, deliver me from it, that I may follow you in complete and constant gratitude, in Jesus' name, amen.
