A Very Brief Primer on the Questions of Omniscience, Omnipotence, and Immutability



I recently had a conversation with a friend about what it means that God “never changes.” He was raised in the church, but never really talked through these issues. He knew that God is all-knowing (omniscient), all-powerful (omnipotent), and never-changing (immutable); but really, what does that mean? For him, and you, here is a very quick primer on three ways Christians have answered that question.

These are broad overviews of four ways of thinking. They are generalizations, each of which represents a dozen related viewpoints with their own nuances and variations. Before someone jumps in with a “well, actually. . .” If you have that level of study, this piece of writing isn’t for you.

Also, there are many more answers to this question than the three I present here, but I believe these three answers fall well within traditional Christian orthodoxy. There are folks within each view who think all the others are going to Hell, but I let my umbrella provide a little more dry ground than that. And, yes, each view has a dozen or more Bible verses to support it. These are all “biblical.”

Calvinism

Regarding omniscience, Calvinism argues that God knows everything, because he determined everything that would happen in advance. Every moment of every day, every decision, has been decided ahead of time. God knew what you would have for breakfast today before you were born. God knows everything because he has planned everything to work together toward his end goal.

How does this impact omnipotence (all-powerfulness)? God possess all power, he created, directs, and controls everything. He has all power.

How does this impact immutability (unchanging)? God never changes in any way. His character remains the same, always. God never questions himself, never changes his plans, never changes his mind.

How does this impact human free will? Calvinism asserts that humans have free will to make their own decisions, but – I’ll be honest – I’ve never heard a really compelling explanation of how.

 

Arminianism

This view also affirms that God is all-knowing, but rather than dictating every moment and every decision, God’s knowledge extends to every possible outcome of any decision. While he may not know what we will do, he knows what will happen regardless of what we do. Also, while we have the freedom to choose any path, God’s encompassing knowledge often allows him to predict our actions, while still allowing us the freedom to choose.  For example, I know that my son will never ask for pancakes for breakfast, because he hates pancakes; yet, he has the freedom to request pancakes whenever he wants.

To summarize: God’s knowledge extends to every possible outcome of every possible decision, spanning all of time. His power allows him to work with our freedom to direct history towards his final, decided outcome. All paths eventually lead to him, so we are free to take any path we want. God’s character does not change, nor do his plans. He does demonstrate some flexibility in the way his plans are achieved.

Open Theism

Open theism also affirms that God is all-knowing, all-powerful, and unchanging. God possesses knowledge of all that exists and has ever existed. However, the future has not happened yet. It doesn’t exist. It is impossible to know what doesn’t exist. Therefore, at any moment in time, any decision a human faces, there is the possibility that God will be surprised. As in the Arminian view, God knows everything about us. He is often able to predict what we will do in a given moment, but we still have the freedom to choose. More than that, he doesn’t know where this decision will lead us.

Being all-powerful, God is able to respond to our decisions on the fly. He can adjust and adapt his plans to work towards his goals; but we have the power to resist and frustrate those goals. God doesn’t get what he wants all the time. While I don’t fall into the open theist camp, I think this is a compelling answer to the problem of evil and pain. God has a plan for where he wants the world to go, but gives us the freedom to make our own plans. We are invited to work with God to make this world a better place; but allowed to be selfish jerks, and he works with that as well.

This is a dynamic view of God, his character never changes, but his plans are constantly changing. This is a God who has the knowledge and power to adapt to the situation.

 

Throwing Down My Marker

Because some folks in the world can’t read an author without knowing where they stand, I’m in the Arminian camp, with some sympathy for Open Theism. However, I don’t believe this is a salvation critical issue. While I might have strong disagreements with those in other camps, or even within my own camp, these are all members of God’s family.

Conclusion

The picture attached to this post is AI generated. It's a picture of the sun setting over Bryce Canyon. Bryce Canyon faces east. It's impossible. That's what this post is, a discussion of impossibility. It is fun, maybe even important, to discuss the attributes of God, but in doing so we need to remember we are discussing things we can't understand. A seasoning of grace is vital.
