Well it was a long time coming but finally it's here. Scentists have finally unearthed the explanation as to why "dim" people (people who aren't as smart as Richard Dawkins) feel the need to believe in a Deity.
Romans chapter one tells us that this really is the great big cosmic duh!!
For the wrath of God is revealed from heaven against all ungodliness and unrighteousness of men, who by their unrighteousness suppress the truth. For what can be known about God is plain to them, because God has shown it to them. For his invisible attributes, namely, his eternal power and divine nature, have been clearly perceived, ever since the creation of the world, in the things that have been made. So they are without excuse. For although they knew God, they did not honor him as God or give thanks to him, but they became futile in their thinking, and their foolish hearts were darkened. Claiming to be wise, they became fools (Romans 1:18-22)
Next time you talk to an atheist remember that the issue to contend over is not knowledge but morality. The atheist loves his sin and suppresses the truth in unrighteousness. Their only hope is that God would open their eyes to their need for the righteousness found only in Christ. The Lord Jesus said "Blessed are those who hunger and thirst for righteousness, for they shall be satisfied" (Matthew 5:6). My precious brother in Christ, Kirk Cameron, says that "you can lead a horse to water but you can't make him drink . . . but you can salt his oats". That salt for the atheist is the fervent preaching of sin, righteousness, and judgment using the law of God as a mirror to help them see their true wretchedness. They need to see that it is their love for sin and not the lack of evidence that causes them to deny God's existence.
It is also important to remember that a belief in God does not translate to someone becoming a Christian. Belief in God is akin to stating the obvious and an outward sign that the atheist has finally humbled himself. He must be born again in response to hearing the Christian Gospel.
1Co 1:21 For since, in the wisdom of God, the world did not know God through wisdom, it pleased God through the folly of what we preach to save those who believe.
