Batter my heart, three-personed God

The literary term used in the first quatrain of this poem is a paradox. The paradox is "three-personed God". It is impossible for one thing to be three persons but I think it alludes to the divine trinity. The speaker is talking of all three parts of God and what God does with all three parts. He seeks to mend, make me new, and defends us. Those are the three lenses of God that the speaker talks of. His diction shows his love for God but the struggle endured because of the "enemy". THe enemy is the devil or sin which we, as humans, are so inclined to do. This poem is almost a begging prayer for help to be more involved with God.
