If you had nothing to do with the commssion of the sin, there's two ways you can still be burdened by someone else's sin. First is thru a generational (family) spirit, the sins of the father passing down to his generations; the second is thru the sins of a spousal partner, the two being one if one is afflicted the two is too. You can put a leash on them thru daily prayer, but to really get rid of them takes fasting, prayer, and intercession.
