The Adventures of Jeremiah is a Christianity-inclined comic that was run in Christian magazines since around 1983. It focused on the lives of 5 teenagers (Jeremiah; Trudy, Jeremiah's girlfriend; Luke, Jeremiah's best friend; Matt, the wisecracker of the group; Penny, Luke's sister and Matt's on-and-off girlfriend) as they tried to keep their faith while dealing with the (quite unusual) tasks of everyday life.

The classic black and white collection can be found here, and the newer colored issues are here.
