Theodoret Quote

The sun by the action of heat makes wax moist and mud dry, hardening the one while it softens the other, by the same operation producing exactly opposite results; thus, from the long-suffering of God, some derive benefit, and others harm; some are softened, while others are hardened.

As quoted in Dictionary of Burning Words of Brilliant Writers (1895), by Josiah Hotchkiss Gilbert, p. 263.
