The Omniscience of God
Introduction:
But the Lord Jesus Christ possessed attributes which we have not; he was omniscient, and therefore he could read Peter’s heart. It was not necessary for him to do what it might be lawful and even needful for us to do. He knew that Peter’s heart was right notwithstanding all the evil of which he had been guilty. So, instead of refusing to have fellowship with him, the Saviour first eats with him,—Christ literally bids him come to breakfast
In contrast to our knowledge, which arises from the passive conformity of our minds to given truths or objects, God’s perfect knowledge follows from his active willing as the Creator of all.
In addition God is conscious of and knows all that exists outside his being. Scripture nowhere even hints that anything could be unknown to him. True, the manner in which he obtains knowledge is sometimes stated in striking anthropomorphic language (Gen. 3:9ff.; 11:5; 18:21; etc.), but he nevertheless knows everything. The notion that something should be unknown to him is dismissed as absurd.
Thomas Watson observed years ago, God’s knowledge is primary, for he is the pattern and source of all knowledge from which others merely borrow; his knowledge is pure, for it is not contaminated by either the object or its sin; his knowledge is facile, for it is without any difficulty; it is infallible; it is instantaneous; it is entirely retentive. God is perfect in his knowledge.
A. W. Tozer observes, “In the divine omniscience we see set forth against each other the terror and fascination of the Godhead. That God knows each person through and through can be a cause of shaking fear to the man that has something to hide—some unforsaken sin, some secret crime committed against man or God.”2
