There is so much to say about Grace both in the definition and its context. Here are a few key grace points by way of summary. For example, New Testament Grace cannot be understood from an Old Covenant point of view.
It may sound slightly presumptive to say “another grace revolution”, but the last big revolution about Grace (after Paul) was back in Martin Luther’s day, 500 years ago. “Revolution” does sound like a strong word to use to use in the context of Grace. However, in light of the need of ‘governmental shift’ or a change or even overthrow of the ‘old regime’, it is an appropriate word to use and at least I may have your attention. We do need to push Grace back to the forefront.
