I think I understand what you are saying.
If the temporal events are a fulfillment of His eternal purpose, then would you say that those temporal events were eternally fully known? If so, then how can anything ever be conceived as a purpose?
I understand that I'm not formulating my questions as well as I'd like, but I'm trying to understand how it is perceived by Calvinists (and apparently others) that all things have eternally been present in the mind of God and yet Him having the ability to create or conceive anything in His mind.
I'm not sure I understand this. Please elaborate.
In my estimation, we are guessing because we are trying to apprehend the mind and purposes of God (finite cannot apprehend infinite).
Rather, I would redirect some of these questions for a different appreciation:
1) God is infinite which means He is beyond our ability to completely grasp. My dog knows to go potty outside, but I don't think she knows why. She can only comprehend so much with what God has given her.
We likewise, have finite limitations.
2) Nothing is outside of God. This is a complete paradigm shift in our thinking from ourselves. We think mostly about things completely outside of ourselves in finiteness because we are finite. It is natural for us to do so, but God has given us glimpses and directions for how to think of Him.
Isa 40:18 To whom can you compare God? To what image can you liken him?
Isa 40:25 "To whom can you compare me? Whom do I resemble?"
says the Holy One
Isa 40:27 Why do you say, Jacob, Why do you say, Israel, "The LORD is not aware of what is happening to me, My God is not concerned with my vindication"?
Isa 40:28 Do you not know? Have you not heard? The LORD is an eternal God, the creator of the whole earth. He does not get tired or weary; there is no limit to his wisdom.
Isa 41:28 I look, but there is no one, among them there is no one who serves as an adviser, that I might ask questions and receive answers.
Isa 43:10 You are My witnesses, says Jehovah, and My servant whom I have chosen; that you may know and believe Me, and understand that I am He. Before Me no God was formed, nor shall there be after Me.
Isa 43:11 I, I am Jehovah; and there is none to save besides Me.
Isa 45:18 For so says Jehovah the Creator of the heavens, He is God, forming the earth and making it; He makes it stand, not creating it empty, but forming it to be inhabited. I am Jehovah, and there is no other.
Isa 45:21 Declare and bring near; yea, let them take counsel together. Who has declared this of old? Who has told it from then? Is it not I, Jehovah? And there is no other God besides Me; a just God and a Savior; there is none besides Me.
Isa 46:9 Remember former things from forever; for I am God, and no other is God, even none like Me,
Continuing:
Joh 21:17 He said to him the third time, Simon, son of Jonah, do you love Me? Peter was grieved because He said to him a third time, Do you love Me? And he said to Him, Lord, You know all things, You know that I love You. Jesus said to him, Feed My sheep.
Col 1:16 For all things were created in Him, the things in the heavens, and the things on the earth, the visible and the invisible, whether thrones or dominions or principalities or powers, all things were created through Him and for Him.
Col 1:17 And He is before all things, and by Him all things consist.
Philosophically, that is, by our reasoning, we understand that nothing exists without God. As the scripture tells us that all things consist by Him, the extent of our actions and thoughts must flow from His sustaining them. Whatever proceeds, then, must necessarily originate in Him as the source of all things. As I said, we think about things as separate from ourselves. Beside God, there is nothing. He is the whole of His being.
Logically as well, we know that He is infinite and yet we comprehend this by thinking spatially. When Jesus says "God is Spirit, and those who worship Him must worship in Spirit and truth" He is telling us that our apprehension of this must transcend the physical.
Let us consider Enyart's question: "Can God write a new song?" In answering, we have to take into account at least two things, that it would necessarily exist only by His sustaining power, and as such, that power has always existed. Also, we must recognize our own finiteness. For us, things are new because we are finite. That is, if we see something outside of ourselves, it is indeed new to us.
An illustration: There is nothing new to my body. I didn't wake up today with anything different. It would be kind of silly to ask if I could have a new arm today. It isn't a restriction on my being and certainly doesn't make me a stone. To say I'm 'stuck' this way isn't very meaningful to any of us. I am exactly what I'm supposed to be and need nothing 'new' to define my physical body meaningfully. In the same way, we have things that simply don't need addition. I don't have to go out and buy new furniture, my house if fully furnished. Now of course we experience change and the need for change because of the very fact that we are finite (things expire, things need to progress for us). We can't buy anything new for the God who has everything. He already owns it, even if we tried. That thing, whatever it may be, comes into being by Him. It is a finite thing dependent upon the infinite for its existence.
In a nutshell, this is the crucial point. God is independent and we are fully dependent. God is infinite, we are finite. God is the primary cause of all, we and what we do is secondary. Philosophically then, I would submit that God is all He will ever be because there is nothing outside of Him, and, being infinite, He is already wherever, whenever, and however anything will be because everything proceeds from Him and consists "...without Him, nothing would exist, that exists..."
I know I haven't said anything definitive here, I'm just trying to broaden the questions in hopes that we will see both our finite apprehension and catch a glimpse of our infinite God (such is the purpose of my sig).
In Him
