John of Damascus — on Dan 2:20 (ORTHODOX FAITH 1:14)

“Further, the divine nature has the property of penetrating all things without mixing with them and of being itself impenetrable by anything else. Moreover, there is the property of knowing all things with a simple knowledge and seeing all things simply with his divine, all-surveying, immaterial eye, the things of the present, and the things of the past and the things of the future before they come into being. The divine nature is also sinless, and can cast sin out and bring salvation. And all that it wills, it can accomplish, but it does not will all it could accomplish. For it could destroy the universe, but it does not will so to do.”
