I committed a past sin. It was before i was saved. Its something really bad and involved my sister. I dont even know if she remembers anything but i feel like i need to confess it to her. However its gonna cause major issues. I cant get any peace about it. I know im forgiven now because its under the blood and i am now saved. I keep going back the Jimmy Swaggart. When he cheated on his wife he confessed it to and obviously repented. But why did he have to tell the whole world? I really need your prayers and help
