The Creator and His Creation
"For what can be known about God is plain to them, because God has shown it to them. For his invisible attributes, namely, his eternal power and divine nature, have been clearly perceived, ever since the creation of the world, in the things that have been made. So they are without excuse. For although they knew God, they did not honor him as God or give thanks to him, but they became futile in their thinking, and their foolish hearts were darkened. Claiming to be wise, they became fools, and exchanged the glory of the immortal God for images resembling mortal man and birds and animals and reptiles." (Romans 1:19-23)
The purpose of this and following essays is to explore a dichotomy. On one hand, it is the nature of fallen man to worship the creation rather than the Creator, and yet we cannot know God, and thus worship him, apart from his creation.
The passage above does not make as exclusive a claim as to say that creation is the only means by which people can know God. Here Paul simply says that creation is a means, and does not address the possibility of other means. But in this essay I am going to show how, since we are carnal creatures and God is transcendent Spirit, any interaction between the two requires some form of God's creation as an intermediary interface.
Abstractions
To begin with, it seems that many people tend to associate God's creation exclusively with the physical realm. But God's creation has a much larger scope than that, for God has also created things that are spiritual and things that are abstract. (Colossians 1:15-16, Psalm 148:2-5)
This can be particularly observed in the way that people can idolize abstractions. For example, I frequently idolize things such as knowledge, being right, flexibility, and logic. Unless someone can prove the existence of some third category, everything we know of reality can fall into two categories: God and his creation. Either something is God or it is something he created. That means it is only possible to idolize things within the category of his creation, because worshipping God is not idolatry. Thus it can be reasoned that if it is possible to idolize a thing, that thing must be a part of God's creation, and is not God himself. So that provides us with a method by which all manner of things can be tested: whatever a person can idolize is a thing created.
If that is the case and it is possible to idolize things like logic and mathematics, then those things must have been created by God and are not inherent attributes of God. Yes, God is logical, but the idea of logic is a human construct; an abstraction derived from observing consistent phenomena. When we speak of logic, we are actually speaking of a conclusion humanity has arrived at through observing creation.
The Holy Spirit
As to my proposition that we can only know God through creation, someone might point out the existence of the Holy Spirit. Isn't that God directly dwelling within Christians and communicating with them? I am open to the possibility that there is some limited capacity through which a person can know God apart from creation, particularly since that would not contradict any of my later propositions on this subject, but I don't see any evidence to justify that possibility. Someday I would like to write a series of essays on the nature of spiritual things in general, and the Holy Spirit in particular, but for now I will simply list the few key points on the matter of the Holy Spirit that directly relates to this subject.
"These things God has revealed to us through the Spirit. For the Spirit searches everything, even the depths of God. For who knows a person's thoughts except the spirit of that person, which is in him? So also no one comprehends the thoughts of God except the Spirit of God. Now we have received not the spirit of the world, but the Spirit who is from God, that we might understand the things freely given us by God." (1 Corinthians 2:10-12)
At first glance this passage may appear to suggest that we can know God apart from creation, but that is not what it is saying. Three times it uses the same Greek word for knowing, comprehending, and understanding. This is a function of the mind. Of course everything comes from God, but by the time those things reach the stage where they are in our mind and are being used by our mind, they have been filtered by many created things. For the full weight of this, read the first few chapters of Isaac Watts' excellent book on Logic, which thoroughly explains all the various steps employed by the human mind in perceiving, conceptualizing, and utilizing ideas.
The Holy Spirit and the Bible
"If you abide in me, and my words abide in you, ask whatever you wish, and it will be done for you." (John 15:7)
"and the sword of the Spirit, which is the word of God," (Ephesians 6:17b)
(Also 1 John 3:23-24, Psalm 119)
There is a close connection with the Holy Spirit and the Bible. The Holy Spirit reveals things through the Bible, and they will never conflict with one another. Even though the Holy Spirit is the direct Spirit of God, it still works through the physical/mental word of God.
Those are my primary arguments in favor of the idea that we can only know God through creation. This essay was mainly background to justify later essays exploring the challenges of reconciling our tendency to idolize creation with our need to see God through it.
