Christians: Is there free will or sin in heaven since there can't be both?

that's not a smart question cause sin is something that keeps you away from god, god doesn't judge you for things you do he judges you for thing you want to which means he goes to the source fo your sin which is the bad stuff in your heart, only way to get that bad stuff out of your heart is to let jesus clean you... so yea you do have free will and on earth you also have free will like the free will not to believe in him or the free will not to worship him or the free will to sin...
