This is a short excerpt from Dr. Ronald Nash from Reformed Theological Seminary in which he gives a brief walk thru of the Conceptual Argument for God's existence. This unique and interesting argument is one of the most fascinating ones that can be used to point a sincere truth seeker towards the definite existence of God.
While most naturalists and materialists would/will scoff at this idea, there is no plausible explanation from those world views as to how/why abstract objects such as numbers, the laws of logic, mathematical equations, geometric shapes exist as universal concepts in the mind of man. If these are unchanging, transcendent concepts and ideas, then a strong worldview must give a plausible explanation for them.
The formal argument goes like this:
1. Either eternal, unchanging, necessary ideas exist or do not exist.
2. Eternal, unchanging, necessary ideas do exist.
(i.e. numbers, geometric shapes, laws of logic and mathematics, etc...)
3. These ideas either exist independently, originate from human minds, or originate from an eternal, unchanging, necessary Mind - God.
4. These ideas do not exist independently.
(Platonism - metaphysically incoherent)
5. These ideas do not originate from human minds.
(The laws of logic, mathematics, geometric shapes, numbers have existed long before man arose)
6. Therefore, these eternal, unchanging, necessary ideas originate from an eternal, unchanging, necessary Mind - God.
(Note: The number of these concepts and ideas is infinite in number, so this necessitates that this Mind posses infinite knowledge - omniscience.)
