The Attributes of God and Justice
Part 3: Omniscience
God possesses attributes which are characterized in two categories: incommunicable and communicable. Those attributes which are incommunicable are those that He holds uniquely to Himself and does not share to any degree with human beings. An attribute which is communicable is one that God possesses and exemplifies but is also one which humanity can possess to a degree.
Omniscience is one of God’s incommunicable attributes. This means that God knows all things. He knows all things that can possibly be known (I John 3:20). This also means that God’s knowledge is complete and there are no gaps that need to be filled in His understanding or awareness. This applies not only to knowledge of the past and the present, but knowledge of future events as well (I Samuel 23:11-13).
Because God knows all things, He knows about our lives as well, even when we are dealt with unjustly. God told Moses, “I have observed the misery of My people in Egypt, and have heard them crying out because of their oppressors, and I know about their sufferings” (Exodus 3:7, HCSB). Because God possesses complete knowledge of past, present, and future truths, He is never surprised.
