Trinity - Big Theological Words

We'll be continuing our series on Big Theological Words with "Trinity" - a word/concept/reality that is simultaneously central to Christian faith and unfathomably mysterious.
As you have opportunity, consider speaking/reflecting/praying the following Trinitarian prayer, an Eastern Orthodox formula adapted by theologian NT Wright:

Father almighty, maker of heaven and earth: Set up your kingdom in our midst.
Lord Jesus Christ, Son of the living God: Have mercy on me, a sinner.
Holy Spirit, breath of the living God: Renew me and all the world.
