In this episode, we give an introduction to the biblical concept of the gospel, which is the message about the good news of salvation that has been accomplished in the life, death, resurrection, and ascension of Jesus Christ. We describe the need for this gospel and the role that the gospel plays in the life of the church and in the life of the individual believer.
A wonderful book that covers this topic much more thoroughly is "The Gospel's Power and Message" by Paul Washer
