Many people get shaken up by the latest big words and fancy ideas coming from dead souls called atheists and scoffers. This ought not to be. Romans chapter 1 tells us that they KNOW God is. Yes, yes, some of them have lied to themselves so many times that they begin to believe there is no God--BUT--things like guilt, hurt, hatred, despondency, need, and emptiness still plague these people. Their emotions, desires and actions cannot be adequately explained through their evolutionary world view. It's hard on 'em to figure it all out. Psychiatrists are making a killing.
Let's look at Romans chapter 1:
1:18 For the wrath of God is revealed from heaven against all ungodliness and unrighteousness of men, who hold the truth in unrighteousness; 1:19 Because that which may be known of God is manifest in them; for God hath shewed it unto them. 1:20 For the invisible things of him from the creation of the world are clearly seen, being understood by the things that are made, even his eternal power and Godhead; so that they are without excuse: 1:21 Because that, when they knew God, they glorified him not as God, neither were thankful; but became vain in their imaginations, and their foolish heart was darkened. 1:22 Professing themselves to be wise, they became fools, 1:23 And changed the glory of the uncorruptible God into an image made like to corruptible man, and to birds, and fourfooted beasts, and creeping things.
Now see there? The Bible tells us all about the scoffer and the atheist. They KNOW He is real. So next time somebody gets in your face about YOUR God, there is no need to be shaken in mind. Just give them the reason for the truth that lieth within you--Christ crucified and risen. If they don't want to hear it, just shake the dust off of your feet and move on. There is somebody that wants to hear.
