My wife used to work for a couple that were atheists. They would celebrate Christmas just like everyone else, tree, gifts, decorations, etc. In fact it was their favorite holiday (holy day). I just don't believe Christmas for most has anything to do with Christ. I personally avoid it.........
If God always intended for the earth to be destroyed then why did he create it to begin with? Would you if you had the power to create life make something simply to be destroyed? I'm sure we all agree that if God wanted to, in a blink of an eye he could return the earth to paradise condition...
