Why can't we see God?

Why can't we see God?
First thing that pops to mind is the fact that we would die if we saw Him. So, He's really doing what's best for us by not letting us see Him...
Why would we die if we saw Him? Because we have sinned. God meant for us to see Him, but with sin in our DNA, we simply can't. God can not be defiled even by the sight of sinful eyes. And we are all responsible for our sin, it is impossible to say that it's not our fault. So because of this, we can't see God.
If God made us to see Him, that implies that to see Him is good. And if it is good, it's what God wants. So contrary to what we might think, God WANTS us to see Him. It pains Him that we can't.
So, we cant see God because we are sinful. But He wants us to be able to... So much so, that He came to earth in the humblest of ways (He, who has all the power in the world) and died to atone for our sinfulness. Because of this, we can accept His gift. And when we do, He promises that we will be able to see Him. Not in this life, with our still sinful eyes, but in the life to come, when He has made us pure.
Kinda makes up for not being able to see Him now, even if it is hard right now. :)
