I am perfectly clear.<quoted text>
I don't think you quite understand the meaning of the word "revelation"
We are all born with a knowledge of Gods existance.
People have three responses to that knowledge typically.
1. They seek to embrace it.
2. They seek to run from it.
3. They seek to destroy it and deny it.
Atheism is clearly in the third group.
The carnal heart is so contrary to God and so antagonistic towards Him that it will even deny reality to preserve itself.
And this is really what atheism is founded, an attempt to destroy God and His revelation to humanity.
There are two choices the atheist is faced with,(or the anti-theist, which is really the correct term for an atheist).
1. Have the carnal nature destroyed.
2. Destroy God and all knowledge of Him.
The desire to destroy God can be so powerful that the carnal mind and heart will even come to the place where it has so obscured the knowledge of God, that it will self deceive itself to protect itself.
It will deny reality in order to maintain itself.
This can be evidenced very simply by the arbitrary and contradictory belief systems of those that want to destroy God so they can preserve their rebellion and carnal nature.
