Some worldly wise skeptics have come up with a brain-teaser as so-called proof that God is not real.  The question goes like this... "Can God create a rock so big that even He cannot lift it?"

And here's their theory...

• if you answer NO, they argue then God cannot create the rock, therefore He doesn't exist.
• If you answer YES, they argue then God cannot lift the rock, therefore He doesn't exist.

Well, the answer is NO, and God DOES exist.  God cannot create a rock so big that he cannot lift it becuase He is infinite in size.  A rock is finite in size.  Beyond that, God can only do what is in his nature to do.  For instance, God cannot lie.  God cannot cease to exist.  God cannot sin. 

P.S. - God is not impressed by worldly wisdom (1 Cor 1:27 .)

Here's one for the world-wise skeptics:  Which came first, the chicken or the egg?  
Not a riddle for me, the chicken came first.  Genesis 1:24 says God created the creatures of the land, not eggs.
