another post defining the Gospel. this one is excellent. check out the whole post, but here is the meat of the coconut:
So what is the gospel?
Although this brief survey is far from complete, it consistently reveals that the gospel is good news concerning Jesus and what he did to accomplish salvation for sinners.
In other words, the gospel is objective. It tells us what God has done to save his people. It consists of concrete, historical events, rooted in Old Testament promises, types, and institutions that were fulfilled in Jesus. It promises that all who trust in Christ and his work will receive forgiveness and life. Of course, this isn’t merely a catalogue of events of only historical interest; all of this has massive implications for our lives. But we must not confuse the gospel message itself with the outworking of those implications.
