I am both amused and dismayed by all of the atheists demanding that Christians prove that God exists, despite what is plain to see by the naked eye. The Christian is not compelled, nor required to "prove" God's existence, beyond the way in which God has already manifested Himself to everyone. This demand for "proof" is a proverbial red herring. The atheist is on the outside looking in because of choice. In contrast, the Apostle Paul wrote of the Christian, "For now we see in a mirror, dimly, but then face to face. Now I know in part, but then I shall know just as I also am known" (1 Corinthians 13:12). In other words, even the Christian, despite being filled with the Holy Spirit, to some extent cannot fully know everything about God and the life after death. Therefore, imagine being an atheist, whose continuing quest is to "disprove" and reject the existence of God, thus resists what God has already revealed. Why should God accede to their further frivolous demands of "proof"?
Atheists are themselves the key proof of the wisdom of Romans 1:18-22, to wit: "For the wrath of God is revealed from heaven against all ungodliness and unrighteousness of men, who suppress the truth in unrighteousness, because what may be known of God is manifest in them, for God has shown it to them. For since the creation of the world His invisible attributes are clearly seen, being understood by the things that are made, even His eternal power and Godhead, so that they are without excuse, because, although they knew God, they did not glorify Him as God, nor were thankful, but became futile in their thoughts, and their foolish hearts were darkened. Professing to be wise, they became fools."
