The Glory of the New Covenant Life!

Is New Covenant Life important? What does that really mean? We boast in believing in the whole Bible yet many focus only on the New Testament. Many times when we see those signs and billboards that exclaim 'New Covenant' what they're really saying is that they really only enforce the New Testament.
Jesus Christ is the great mediator of this New Covenant. If you want to understand the Bible, its theme, its purpose you better understand Hebrews chapter 8.
