I am but clay in thy hands, but thou art the all-loving artist;
Parrise I lie in thy sight, yet in my selfhood I strive
So to embody the life and love thou ever impartest
That in my sphere of the finite I may be truly alive.

Knowing though needest this form, as I thy divine inspiration,
Knowing though shapest the clay with a vision and purpose divine,
So would I answer each touch of thy hand in its loving creation,
That in my conscious life thy power and beauty may shine.

Reflecting the noble intent thou hast in forming thy creatures;
Waking from sense into life of the soul, and the image of thee;
Working with thee in thy work to model humanity's features
Into the likeness of God, myself from myself I would free.

One with all human existence, no one above or below me;
Lit by thy wisdom and love, as roses are steeped in the morn;
Growing from clay to statue, from statue to flesh, till thou know me
Wrought into manhood celestial, and in thine image reborn.

There's loads of correspondence going on in this poem. And it starts with the title: "I in Thee, and Thou in Me." The gist: "Thee" = God. "Thou" too. So the speaker is in God, and God is in the speaker. Get it?

Anyway, this correspondence between God and the speaker is emphasized again and again in the poem. In case you couldn't tell.

So the speaker is the work of God, but he also works with God "to model humanity's features/ Into the likeness of God." The speaker also says that he is "One with all human existence, no one above or below me." In other words, there is no distinction between him, other people, and God. It's all one big happy family.

There's a lot of back and forth between "I" and "you" (or rather, "thou") in this poem. This back and forth is important because it dramatizes—you guessed it—the idea of correspondence. The speaker is talking directly to God, and addressing him in a way that suggests that the two really get each other. You'd think God's supposed to "get" everybody, but it's extra when there's poetry involved.

So, the fact that the poem is structured as a kind of conversation or dialogue is pretty key to the idea of correspondence. When we talk to someone—even if it's God—we correspond with them. Another word for communication, after all, is "correspondence." See what we just did there?
