In the past God spoke in a variety of forms. Listen to the opening verses from the book of Hebrews. 'God, after He spoke long ago to the fathers in the prophets in many portions and in many ways, in these last days has spoken to us in His Son' (Heb. 1:1-2a). In Jesus Christ, the Word of God became incarnate. His words are God's words. And His words were God's final and most supreme revelation to mankind. On that holy mountain the Father declared, 'This is My beloved Son, with whom I am well-pleased; listen to Him' (Mt. 17:5). Through Christ, Scripture is complete and sufficient for 'everything pertaining to life and godliness' (2 Pet. 1:3). God designed it whereby no other revelation would compete with that of His Son. From Genesis to Revelation, the Scriptures are closed, and Christ had the final say.
