It's a mystery! (Tozer for Tuesday)

The first spiritual axiom I want to note is that God does everything creative and constructive. He does not do evil. Sin is a work of temporary rebellion against God, and the explanation is yet concealed. Sin is concealed; that is, the reason how the great God can be working and sin can still be in the world is concealed from us. We do not yet know because those concealed things are mystery.—A.W.
