God frequently tells us to be careful in our choices (De_30:19) because they have consequences. (Ga_6:7) He asserts that we have a will, that we are conscious, and that we have a responsibility to choose the good and refuse the evil. (Is_7:15) There is a moral law, and we violate it at our peril.
To all of us, each and every one of us, this is self-evident, that we have the ability to make choices: that we are conscious and aware of the options of both good and evil choices before us, and that we have an obligation to make good choices.
Atheism, however, asserts that only matter and energy exist, and that matter and energy are not conscious. This implies there is no consciousness, thus no free choice, and no good or evil. This implies that our perception of free will and moral choice is merely an illusion in our brains, implying that we are no more than mechanical robots, programmed by evolution to act as we do. Atheists assert this because it is implied by atheism, not because there is any actual evidence for it.
Even Heisenberg’s Uncertainty Principle does not provide for conscious, moral choice; it only provides for the possibility of random, unconscious, amoral behavior.
When accepting proposition A implies conclusion B, and B is false, we know from the logical contrapositive that A is also false. This is called proof by contradiction. In other words, the fact that atheism implies we are not conscious, and that we make no voluntary choices, and that there is no moral reality, conclusions which we know by experience to be false, proves that atheism is false.
It is true that while we are alive in our body we are intimately linked with our brains, which operate with chemicals and electricity, but we are not merely our brains: we are more than bodies. We live through our bodies and think through our brains, but our thoughts are not merely impulses in our brains any more than we are merely our bodies. In other words, we are intimately connected with Nature, but we are not merely of Nature: we are eternal, made in God’s image.
Our ability to think and to choose, to understand Nature, something Nature by itself cannot do, proves we are above Nature, that we exist outside of and apart from Nature, such that we can look at Nature as an outside observer. This is the foundation of epistemology, the science of knowledge, that enables us to perceive, understand and know the living God, and the universe He created.
