  I probably have too much free time to just wonder about these things...but I do and I think maybe you'll like to hear them. I was sitting around outside the other day thinking about God and his physical make-up and appearance. It didn't take me too long to find out what He must look like, since we are told in Genesis that man is made in the "image" or "likeness" of God. Sorry girls, but God IS a man because men were made in His likeness, and women were in man's likeness. Anyways, that doesn't mean that we're made of the same stuff, just that we look alike. I wouldn't even venture to think that He has intestines or anything of that sort, for if you made an image of man, you wouldn't draw his insides. So, thus far we have man looking like God, but not necessarily having the bodily functions of man.
I hope this breaks up any thought that some may have had that He was just this big, glowing light (since we look nothing as simple as a big, glowing light). Now, what is God made of? He can't be made of matter as we know it. God created every atom in the universe, so if He was made of matter like we know it, then He's made of His own creation. That means He'd be His own creation! That's a whole different religion called pantheism in case you were wondering. If you believed He was made of anything that He created then He'd also be subject to His own creation! Then He wouldn't even be God! So...now that that's outta the way...what's He made of?!?! He can't be made of anything we know of because we only know of His creation. So...He must be made out of something we cannot even fathom. It surely isn't something that you could just run your hand straight through, that would make Him seem almost non-existent.
I like to think my God exists, don't you? So, in conclusion, I really don't know what He's made of and it likely doesn't matter as long as you don't think He's made of matter or something that's kinda non-existent... I know its confusing...but its nice to think about...
