How do you think heaven will be like?(christians only please).?

I think we will get all of our hearts desires as long as its not a sin, and we will have free will, but not want to sin. also it will be beautiful, and we can learn new stuff and do things we never got to do on earth.We will also have perfect bodies. Because God is a creative god, I dont think we will be playing harps and sitting around or singing to him all the time, but we will worship him with everything we do and love.
