I was raised Catholic, and had the idea of "inviting Jesus into your heart" doa little confused. Apparently, he knocked all the time, and when you answered, he could come inside & be inside your heart. The symbolism of this was somewhat lost on me though - I routinely used to kick Jesus out of my heart before I did bad things. I would tell him to leave, and once the evil deed was done, I would say, "Okay Jesus, you can come back in now." This went on for years.
