Mike Horton delivered a message during TGC21 titled “The Necessity of Justification,” taking a look back at Luther’s discovery of the doctrine and the many factors that have affected its understanding, acceptance, or rejection by believers over the years. Correctly understanding and applying the doctrine of justification, Horton argued, is key to another needed reformation, though it does not stand alone. We must recognize the priority of justification, he encouraged his listeners, while also recognizing and rejoicing in the plethora of other gifts we receive in salvation.
