“In sum, great benefits come to God’s people if they are willing to take seriously the fact that the ‘final revelation’ has come in the Christ of Scriptures. Far from hindering enthusiasm and a sense of the immediacy of God’s presence in their midst, faith in the sufficiency of Scripture will move them to serve him with the full vigor of their beings. It must not be forgotten how the resurrected Christ stirred the hearts of his depressed disciples. The Gospel of Luke explains that Jesus enlivened his followers by opening to them the Scriptures. Beginning with Moses and all the prophets, he explained to them what was said in all the scriptures concerning himself (Luke 24:27). Why? Why did the resurrected Christ speak to them in this way? Why did he not simply give them a new revelation?
The resurrected Jesus opened the scriptures to them because that would be the way by which spiritual life would be sustained for them from this point on. As a consequence of his opening the Scriptures, their hearts burned within them (Luke 24:32). The same principle has continued through all the ages. As the resurrected Christ through his Spirit opens the Scriptures to his people, their hearts have burned within them. Much greater than depending on the stimulus of new revelations of the Spirit is living out the sufficiency of the final word as it is found in the Christ of the Scriptures.
And why not both? Why not the illumination of Scripture coupled with new revelations of the Spirit? Simply because if you declare a need for both, you have implied the insufficiency of the one. You have placed yourself back in the framework of the old covenant, in a time when new revelations were required because of the incompleteness of the old. But Christ is the final word. No further word for the redemption of men in the present age in needed. In Scripture is found all the truth that is needed for life and godliness.
May the Lord grant his church today a full unleashing of its potential that comes from the full knowledge of the truth as it is found in Jesus. For he is the final word.”
