those who claim there is no God are already lying to themselves.
I think that depends upon how they're defining the term "God" though. Some people were brought up to believe God was a tyrant who forbade the idea of premarital sexual intercourse. The reason being that it could lead to the mortal, and unforgivable sin of dancing. In other words, they were brought up with incoherent ideas about who or what God was. When someone is inculcated into a belief system that is incoherent and contradictory, one is forced to become a liar in order to remain in that belief system. Simply leaving that system isn't enough for them to see the truth.
Lying to you is the next logical step. And what discussion can happen under those terms?
An interesting one if the liar believes their lies.
Biblical foolishness is denying God, as the fool has said in his heart there is no God. Why is that foolishness? Because he knows there is one. Creation declares to us God's power.
This is an interesting point because you're explicitly distinguishing between what the fool says in their heart verses what they know, and see with their senses. The examples are many, but let's take the Vietnam combat veteran who has just witnessed his best friend literally blown to so many pieces that there's nothing left to put into a body bag. He see's the Viet cong shooting at planes, ignoring self preservation and the opportunity to flee to safety, as napalm is about to incinerate them. He lives in a world that is nothing less than pure hell, and hell is separation from God. They live with that for the rest of their miserable, tormented lives. For them, there is no God. They know this. Their senses tell them this, and their heart tells them this as well. All they see around them is foolishness.
Saying it's not so does not make it not so.
Quite true, and it is just as true to point out that saying it is doesn't make it so either. There are no double standards when it comes to God.
Every athiest, who lives in creation, knows God exists.
I think this is a bit of a cavalier thing to say. Most atheists rely exclusively upon their intellect and senses, and insist that anything that cannot be observed, doesn't exist. While this isn't exactly an intelligent perspective, it's what they were taught. It's what they believe.
Denial is their answer. Denial to themselves,
If this is true, and it may very well be; I can see how this could be a way for God to reach them. Christ also taught self denial, and anyone who is able to deny themselves is well on their way to Christ.
... to you, to anyone who might want to make them face reality.
No doubt this is a problem, but it is just as prevalent among those who believe God exists. One needn't look any further than the history of the three Abrahamic religions to prove this fact.
They scream and cry there is No God because they're terrified of His rightful judgment.
The theists scream and cry as well, not because of any fear of God's rightful judgement, but to condemn others. If we look at who has a better chance of salvation, would't you agree that those who are terrified of God's rightful judgement are in a better position to receive God's mercy? After all, even God waits until one is dead before carrying out his rightful judgments.
Athiesm is a fallacy in our inability to prove a negative. In all that is, is there something you don't know? Or do you know all that can be known? If not, cannot God exist in that part you don't know? And they will answer, No, He cannot, not because they think it true, but because they are invested in that notion.
Paul also points out that God cannot be known. He corrects himself when he says, "we know God, or rather we are known of him". As a strict monotheist, Paul understands that it is impossible to worship God as an object. It is idolatry to objectify God. In this respect, there is no effective difference between Paul and the atheist. The atheist can't become an idolater in the same way the theist can.
There is no effective difference between Paul and the pagan who understands that one cannot know the Unknown God as well. The problem isn't just that the atheist doesn't believe in God, or the pagan worships what he doesn't know in ignorance. The problem is with ourselves in that we're not following Paul's example by becoming an atheist for the sake of the atheist, or a pagan for the sake of the pagan. Some just may not have that calling, but in a world full of atheists, and pagans, it makes them redundant. One needs to adapt for them as well as the evolutionist.
If we are unwilling to speak to them in their own language, we're no better than the Pharisee or scribe who sees everything in terms of a strict adherence to the Mosaic law.
Unless someone is humble, they will not easily move from serious error. We see that here also.
Yes, we see it everywhere, but the most imortant place to search for it is within our own proud hearts.
