Why Do Christians Continue to Say Someone Who Says God Isn't Real Is a Fool...?

Well it is true. The Bible calls you senseless (Psalms 14:1). The thing is, is that Jehovah hides things from the wise and intellectual (Matthew 11:25). For you have to be meek to inherit the earth (Psalms 37:29). You don't see what is right in front of you. Everything good comes from God. Everything bad that happens around you either comes from man or Satan. And all these good things you see and do not see are a marvel of engineering. They all show Jehovah's power, love, ,and justice.
