Suffering is sometimes a mystery. We must affirm both the mystery and God. The paradox remained, but now, at least, Job knew that it belonged there–that it is built into the moral and physical orders, and into the very nature of God as He has permitted us humans to perceive Him. In a world where the universal principle is cause/effect, the book of Job reminds us that the principle is a reflection of the mysterious,
self-revealing God. It is subsumed under Him, however, and He cannot be subsumed under it. The God-speeches remind us that a Person, not a principle, is Lord.
