I saw a billboard in front of a Church that said I'f you wanna make God laugh tell him your plans. Do you think God laughs? Do you ever think he just plays with his Kids?
We are made in His image and laughter is a fine medicine, so my conclusion is that Heaven will be filled with laughter. Like sitting around watching that funniest video show....God saying, Remember the time....and we all remember and laugh...only it won't be the embarrassing moments, just the real funny ones.
