Compatibilism and the Nature of God's Omniscience
God's omniscience is the attribute by which he possesses perfect knowledge of all things, a concept deeply rooted in biblical texts and theological tradition [2, 5]. This divine attribute is considered infinite and absolute, encompassing past, present, and future events, as well as all potential realities [2]. The full import of God's omniscience is acknowledged as beyond human comprehension [2].
The Bible frequently asserts God's comprehensive knowledge. For instance, Job 22:2 asks, "Can man be compared with God, even though he were of perfect knowledge?" [1]. This rhetorical question highlights the incomparable nature of divine knowledge. Similarly, Job 9:2 states, "Of a truth I know it is so; but how can man be just with God?" [3]. The psalmist, in Psalm 139, extensively meditates on God's omniscience, asserting that God has "searched me, and known me" [10]. Matthew Henry notes that this psalm is a "pious devout meditation... upon the doctrine of God's omniscience" [5]. The psalmist further elaborates that God knows his thoughts, his paths, and his lying down, and is acquainted with all his ways (Psalm 139:2-3). This knowledge is so profound that even before a word is on the psalmist's tongue, God knows it completely (Psalm 139:4).
The concept of God's omniscience is often linked with his omnipresence, as Matthew Henry observes, "God is every where present; therefore he knows all" [5]. This connection suggests that God's knowledge is not limited by space or time. The prophet Jeremiah speaks of God knowing all the works of men (Jeremiah 32:19), and the book of Proverbs states that God's attributes, including wisdom, are eternal and coincident with himself [8]. Jamieson, Fausset & Brown emphasize that God's omniscience and omnipotence enable him to execute immediate justice, indicating that he does not need to "watch" or observe over time, as his knowledge is instantaneous and complete [7].
The New Testament also affirms God's omniscience, referring to his "foreknowledge" in passages like Acts 2:23, Romans 8:29, and 1 Peter 1:2 [2]. This foreknowledge implies that God knows events before they occur. The apostle Paul, in Romans 11:2, states, "God has not rejected his people whom he foreknew." This highlights a specific aspect of God's knowledge related to his divine plan and election.
Theological traditions emphasize that God's omniscience is an essential attribute of his being. John Gill, commenting on Ephesians 4:6, notes that there is "but one God," and this unity implies a singular, perfect, and independent Being whose perfections include infinite knowledge [4]. Jamieson, Fausset & Brown, in their commentary on 1 Timothy 2:5, connect God's unity in essence and purpose with his comprehensive knowledge and offer of grace to all humanity [6]. Adam Clarke, discussing Philippians 2:11, speaks of God the Father exalting Jesus Christ, illustrating how divine attributes are magnified through Christ's work, which presupposes God's complete knowledge of the divine plan [9].
Compatibilism, in the context of God's omniscience, addresses the philosophical and theological question of how God's exhaustive knowledge of future events can be reconciled with human free will. The core tension arises because if God knows with certainty what will happen, it can appear that future events are predetermined, potentially undermining the idea of genuine human choice.
One perspective within compatibilism argues that God's knowledge of future free actions does not cause those actions. Instead, God simply knows what free agents will choose to do. This view maintains that an action is free if the agent could have chosen otherwise, even if God knew what they would choose. God's knowledge is seen as a perfect record of future reality, not a determinant of it. This is akin to observing an event without causing it; God's knowledge is perfect observation across all time.
Another compatibilist approach suggests that God's knowledge is so comprehensive that it includes all possible choices and their outcomes. This is sometimes referred to as "middle knowledge" (scientia media), a concept associated with Molinism. According to this view, God knows not only what will happen, but also what would happen in any given set of circumstances, including what free creatures would choose if placed in those circumstances. This allows God to plan and providentially govern the world while still affirming creaturely freedom. God's knowledge of these counterfactuals of creaturely freedom enables him to create a world where his purposes are achieved through the free choices of individuals.
The challenge of reconciling divine omniscience with human freedom is a long-standing theological debate. However, compatibilist positions generally seek to affirm both God's absolute knowledge and human moral responsibility. They argue that the two are not mutually exclusive but can coexist, even if the precise mechanism of their coexistence remains a mystery to human understanding. The emphasis is often placed on the nature of God's knowledge as perfect and non-interfering, allowing for genuine human agency within a divinely known and ordained framework.
