The first line is the DNA of the poem; the rest of the poem is constructed out of that first line. A lot of it has to do with tone because tone is the key signature for the poem. The basis of trust for a reader used to be meter and end-rhyme.

There is rest in this world nowhere except in Christ, the manifested love of God. Trust in excellence, and the better you become, the keener is the feeling of deficiency. Wrap up all in doubt, and there is a stern voice that will thunder at last out of the wilderness upon your dream.
Frederick William Robertson
