It's not going to be that hard to be in Heaven, or the Heavenly City or the Millennium, but you're going to have something to do and something to keep you busy, and you'd be unhappy if you didn't. Wouldn't it be ridiculous after being so busy here if you wound up in Heaven with nothing to do but sit on a cloud playing a harp for a thousand years?-Much less all eternity! I think you'd really get bored.
