Creatures' comfort is only on the surface
It is only in God that are collected and united all the perfections, which in the creatures are sundered and divided.
If I had everything that I could desire, and my finger ached, I should not have everything, for I should have a pain in my finger, and so long as that remained, I should not enjoy full comfort. Bread is comfortable for men, when they are hungry; but when they are thirsty, they find no more comfort in bread than in a stone. So it is with clothes, they are welcome to men, when they are cold; but when they are too hot, clothes give them no comfort. And so it is with all the creatures. The comfort which they promise is only on the surface, like froth, and it always carries with it a want. But God's comfort is clear and has nothing wanting: it is full and complete, and God is constrained to give it thee, for He cannot cease till He have given thee Himself.
