Moses is standing at a burning bush in the wilderness of Midian, a fugitive tending someone else's flock, and he asks the most reasonable question a person can ask before walking back into Egypt: who are you, exactly? The answer God gives is not a title or a function. It is a statement about how God exists. "I AM WHO I AM" (Ex 3:14). Not "I was," not "I will be," not "I am like." Simply: I AM. That answer is still the best starting point for understanding the God we pray to.
What "incommunicable" means
Theologians distinguish between attributes God shares with his creatures in some measure and attributes he holds alone. Love, goodness, and wisdom are communicable because human beings genuinely possess them, however imperfectly. Aseity, immutability, eternity, omnipresence, omniscience, and omnipotence are incommunicable. No creature has ever possessed them. They describe not what God does but what God is, in a mode of being unlike anything in the created order.
This is not a grid imported from Greek philosophy. The texts themselves make these claims, often in pastoral moments. Understanding them is not about building a more impressive mental model of God. It is about knowing what kind of ground you are standing on when everything else gives way.
Aseity and immutability: the stable core
Aseity means God has no source outside himself. He was not created, did not emerge from prior conditions, and does not require the universe in order to exist. Paul makes this explicit in Athens: God "is not served by human hands, as though he needed anything, since he himself gives to all mankind life and breath and everything" (Acts 17:25). God does not receive worship because he needs it to keep himself going. He is not anxious for resources.
Malachi closes the Old Testament with this: "I the LORD do not change; therefore you, O children of Jacob, are not consumed" (Mal 3:6). The logic is pastoral before it is philosophical. Israel has been faithless for generations. They deserve to be abandoned. God's commitment to his covenant people does not rise and fall with their performance, because God himself does not change. His faithfulness is not a mood. Hebrews applies the same truth to Christians under pressure: "Jesus Christ is the same yesterday and today and forever" (Heb 13:8). The mercy recorded in the Gospels is not a historical snapshot of a past disposition. It is a live description of a permanent one.
Eternity and omnipresence: outside time and place
Psalm 90 opens with a confession that cuts against every anxiety about the future: "Before the mountains were brought forth, or ever you had formed the earth and the world, from everlasting to everlasting you are God" (Ps 90:2). God does not exist within time the way creatures do. The future is not uncertain to him.
David runs through every location he might flee to in Psalm 139 and finds God already there. Heaven, Sheol, the far side of the sea, the cover of darkness (Ps 139:7-10). None of it works as an escape. David's register in that psalm is wonder, not dread. Omnipresence means there is nowhere God's care cannot reach. For a person in exile, or in a hospital room far from anyone who knows them, that is not abstract. It is geography.
Omniscience and omnipotence: no ceiling, no resistance
"Great is our Lord, and abundant in power; his understanding is beyond measure" (Ps 147:5). The Hebrew behind "beyond measure" is literally "there is no number." God's knowledge has no blind spot, no information gap that prayer is filling him in on. He knows what you will ask before you ask it (Matt 6:8), which raises an obvious question: why pray at all? Because prayer is not an information transfer. It is a relational act between a creature who depends entirely on God and a God whose knowledge of the situation is already complete. The asking itself is part of what God intends.
Job reaches the end of his long argument and hears from the whirlwind. The questions God asks are unanswerable by design: where were you when the foundations were laid, who shut the sea with doors, can you bind the chains of the Pleiades (Job 38:4, 8, 31)? Job's response is not defeat but clarity: "I know that you can do all things, and that no purpose of yours can be thwarted" (Job 42:2). He came looking for an explanation of his suffering. He got a demonstration of who God is. That turned out to be enough.
Why these are pastoral anchors, not cold facts
There is a temptation to treat divine attributes as the dry section of systematic theology, something to summarize and move past on the way to application. That instinct has it backwards. The attributes are the application. Consider what it means to pray to a God whose knowledge has no ceiling, whose power faces no resistance, who does not change his mind about his people because he does not change, and who is present in every location without exception. That is the most stable thing in the universe.
Compare that with what happens when we pray, in practice, to a smaller God. A God who might forget. A God whose attitude toward us might have shifted since last week. That God produces anxious, transactional prayer. The incommunicable attributes do not make prayer unnecessary. They make real prayer possible, because the person you are bringing your need to is actually adequate to it.
Psalm 77 is a good example of how this works in practice. Asaph is in anguish and says God seems to have forgotten to be gracious (Ps 77:9). But he does not conclude that God is therefore unreliable. He turns to the history of what God has done at the exodus and grounds his present distress in the character of a God who has not changed since then. Immutability is doing the pastoral work inside the lament.
Peter can write "cast all your anxieties on him, because he cares for you" (1 Pet 5:7) only because the God he is describing has the capacity to bear that weight. Unlimited power, unlimited knowledge, unlimited presence, unchanging character. Anything less and the invitation collapses under its own weight. These attributes are not a wall between God and his creatures. They are what makes God a safe place to bring the full weight of human need.
Before your group meets this week, open to Psalm 90:2 together, and ask each person to name one situation where they have been praying to a God they have functionally made smaller than he is, then read the verse aloud as an anchor, not a rebuke.
