And you know this... How?
Mark
Every knee shall bow my friend....It is like gravity my friend, you may choose not to believe in the effects of gravity and even ignore the evidence all around you. But one day you will come into direct conflict with the reality of that truth.
George Carlin denied the existence of God all his life, and you are welcomed to do the same. However at the end of the day all the denial that your profess will not have an once of effect that He is God.
Now you need to ask yourself if what you have heard about the nature of God is actually true? Or have you just believed what you wanted to believe? In my case I know He is the kindest and most loving person I know...
I would encourage you to find out for yourself, let me know if I can help.
