Who needs the Gospel?

Who needs the Gospel? The word Gospel means big news (not good news because it is good news to those who are saved and bad news to those who are not). Christians use it to mean the big news about Christ. But sometimes Christians can get into the habit of thinking that the Gospel is something that is only preached to non-Christians. But the reality is, that it doesn't matter where you are in life or in your Christian life you need the Gospel. Paul sees the Gospel as the thing that saves non-Christians and continues to save Christians:

¹Now I would remind you, brothers, of the gospel I preached to you, which you received, in which you stand, ²and by which you are being saved, if you hold fast to the word I preached to you— unless you believed in vain. (1 Corinthians 15:1-2)
