There is a basic principle about satan, his subjects and satanic atheism that true Christians should thoroughly understand and always keep in mind. The principle is this: Whatever way satan, his evil or his subjects speak evil of God or His righteousness, the same is invariably true of satan, his evil and his subjects. Since atheism is a product of satan, it follows that in whatever way atheism speaks evil of and condemns true Christianity, the same is invariably true of atheism.
Atheism accuses Christianity of being very closed-minded and prides itself in being open-minded. However, the reverse is true. Atheists are some of the most - if not the most - closed-minded subjects of satan there are on earth. The reason this is so is that they close their minds to the existence of the true God, who is omnipresent, omniscient, omnipotent, etc., and focus their depraved attention on the paltry works of totally depraved and cursed humanity and on their minute and everchanging appearance of "knowledge" about nature.
The totality of everything God's Elect (righteous mankind) should rightly reject and close their minds to is far less than that to which atheists wrongly close their minds. The God whom true Christians serve is infinitely greater than anything the minds of atheists are open to, and it is to this infinitely Greater One that the minds of atheists are closed. Since the Almighty God is greater than all of His creation, atheists are far more closed-minded by virtue of rejecting the Greater One, and true Christians are far more open-minded by accepting, being united to and placing their faith in the Greater One.
But the depraved minds of atheists go beyond being closed to the Almighty God, His glory and His righteousness. Their foolish and insane close-mindedness also extends itself to the existence of a great portion of God's creation, such as heaven, angels, hell, the lake of fire, demons, etc., because of their disbelief of their existence.
They also close their minds to the most important aspect of human existence, which is the human soul. They thereby close their minds to part of their own existence. Who but utterly insane people would admit that they have corporeal bodies while denying that they have heads? Atheists admit that their existence consists of corporeal bodies but deny or close their minds to the fact of the existence of their souls. It is their souls that gives life to their bodies!
This damnable hypocrisy and blindness of atheism are just two of the many ways human depravity is revealed (a fact that atheists also close their minds to). They are part of the overwhelming evidence of the fallen state of mankind. It is from their fallen state that Christ saves His elect of mankind. But alas, insane atheism also causes its subjects to close their minds to the only way of salvation from the eternal wrath of God.
