Romans 1:16 "For I am not ashamed of the gospel, for it is the power of God for salvation to everyone who believes, to the Jew first and also to the Greek."
These listings are a sample of the richness of the Gospel. Each could be a blog post on its own. The point is to show the reader how wonderful the Gospel is and why we need to hear it, read it and tell it to ourselves everyday. By doing so, we as Christians will be reminded of who we are and Whose we are. By telling ourselves the Gospel, we will then desire to tell it to others.
