Jacob had always wanted to serve a mission, but due to some mistakes made before he left, he was unworthy to go. He lied to himself constantly to convince himself that he was okay, which led to him serving for 9 months before the guilt became too much and he had a powerful experience that helped him to seek repentance. Upon returning home, he intended to repent and return to his mission, but life began happening again and he soon found himself committing the same sins. It wasn't until after a few more turning points that Jacob was finally able to forsake his sins, fully repent, and eventually return to his mission.
