Commentaries:
God's will can be known through revelation, which is the supernatural disclosure of God's purposes and instructions through various means such as direct communication, inspiration, visions, dreams, and signs. As mentioned earlier, God has assembled these revelations in the sixty-six canonical books of the Bible, both the Old and New Testaments.
Isaiah 8:16 prophesies that God's testimony—the fullness of His revelation, which Paul calls “the whole counsel of God” (Acts 20:27)—would be bound and sealed among Christ's disciples, establishing the biblical canon for all time. If this is the proper interpretation of this verse, it precludes any “new revelation.” We have in God's Word all we need for salvation.

The Model Prayer (Part Five): Your Will Be Done
Even mysteries of prophecy are revealed for the purpose of salvation so that we might be better motivated, and therefore He deemed it helpful for us to know, not for purposes of vanity, but that we might be more precisely motivated to keep His law, as this verse clearly instructs. In other words, the revelation of prophetic truth is given that we might pay better attention to conduct.
