I was just reading a blog in which the author thinks that one of the interesting theological questions of the not too distant future is the meaning of the Gospel. This idea intrigued me enough to decide to ponder it here.
As I think about it, I think about what one of my teachers taught us. That the message of the Gospel is to proclaim the death, burial and resurrection of Jesus. I also think about how widely used the word is these days to identify a curriculum or name a blog or website or clarify your mission.
When you think of the Gospel, what do you think about? How would you define it? What is your understanding?

Your post has an interesting dilemma – The title is the meaning of the gospel but the main discussion in the post is the message of the gospel. Are these two the same thing?
The message of the Gospel – Man can live in peace with God through Jesus
The meaning – Life starts from now; you can be free; there is hope; there is a plan; things aren’t going to stay this way for ever.
