God wants us to worship Him only because that's the only way to get in heaven. He commands it out of love for us, not pride for Himself.
but god created heaven, therefore he decides how to get into heaven. He is choosing to eternally damn people just because they don't believe in him
No, you don't understand the concept of heaven.
God did create heaven. Heaven is a perfect place. Sin is NOT allowed in heaven, or else it isn't heaven. Think of it like a highly selective school. To get in this highly selective school, you need to be smart. If you get in without being smart, then it isn't highly selective.
So you can't get into heaven with sin.
Now, all of us sin. We are born sinners since we have descended from Adam (we actually didn't have sin until Satan tempted Adam and Eve). So since we all sin, we shouldn't get into heaven at all, right?
Well, God forgave us of our sins by sending Jesus to die on the cross FOR our sins. If you believe in Jesus Christ (essentially God), worship Him, and let him into your heart (sounds sappy, I know), then your sins are forgiven. Then, since your sins are forgiven, you have no sin, so can go into heaven.
It's not that God decides who gets into heaven. It's you have to be perfect to get into heaven, and the only way to be perfect is to accept Jesus as your savior and worship him.
