I wished to address this point because it's a very common objection to God's knowledge and Free-will. It's predominantly an Atheistic argument but some theists also find it confusing.
The problem with this is we see time as linear. We don't really know what's gonna happen tomorrow. We don't know what choices we will make tomorrow. But God sitting here with us today knows what choices we are gonna do tomorrow. Thus, are we truly making choices when God knows already?
The first point is that, even with this simplistic view, even if God is sitting with us today, and God has knowledge of tomorrow, knowledge is not causation, thus we do have free-will. The choices are not already made for us. We are gonna make the choices. This response is typically a theological response which is made in a philosophical manner. This is also Christian/Islamic argument. In Islamic traditions they called it Cadhr.
The second point is, mathematically one could perceive of a 4D being while we are 3D (dimensional). This is just to conceptualize God's view of our time. A big problem with the argument above is the anthropomorphism. God is not really sitting with us as a man today. God is a transcended being and he transcends time.
A 4D being who is not bound by time perceives time as just another dimension, similar to how we perceive spatial dimensions. Unlike us, who experience time linearly (past, present, future), this being can see all moments in time simultaneously. Imagine how a 3D being can see an entire 2D plane at once; similarly, a 4D being sees our entire timeline at once. They are not moving through time but can observe and interact with any point in time as easily as we move through space.
The rest is just a read that explains this 3D/4D beings. Not necessary to read but just left there for anyone who wants to.
Mathematical Concept
- Dimensions: In mathematics, dimensions refer to the number of coordinates needed to specify a point in a space. For example:
- 3D Space: A point in 3D space is defined by three coordinates (x, y, z).
- 4D Space: A point in 4D space is defined by four coordinates (x, y, z, w).
- Time in Physics: In physics, particularly in the theory of relativity, time is often treated as the fourth dimension, leading to the concept of spacetime, where events are described by four coordinates (x, y, z, t).
4D Being and Time
- 4D Space with Spatial Dimensions: If we consider a fourth spatial dimension (w) rather than time (t), a 4D being would perceive space as having four dimensions: (x, y, z, w).
- Perception of Time: For a 4D being, time (t) might be perceived as a static dimension, like a spatial dimension. This means they can see the entire timeline (past, present, future) simultaneously.
Visualization and Interaction
- 2D Analogy: Imagine a 2D being on a flat plane (x, y). We, as 3D beings, can see their entire plane at once. Similarly, a 4D being can see our entire 3D space (x, y, z) and our timeline (t) at once.
- Mathematical Representation: An event in our 3D space over time is represented as (x, y, z, t). A 4D being might represent an event with an additional spatial coordinate: (x, y, z, w).
The concept of a 4D being not bound by time can be understood mathematically by considering time as an additional dimension that this being perceives all at once, much like we perceive spatial dimensions.
So that's the concept of God's transcendence. He knows that's gonna happen because from his perspective, he sees time as a line below him which he could access. He can see and interact with the future as he pleases just like the mathematical concept of a 4D being. So what's gonna happen in our perspective has already happened in a 4D beings perspective. So we have already done it. That's why he knows. And that's why we still have free-will.
Cheers.
