What does the Bible say about God's revelations in the Old Testament?

Scripture indicates that throughout history, God has made Himself known through revelations in various forms. Hebrews 1:1-2 notes that God spoke to the fathers through the prophets at many times and in various ways, but in these last days, He has spoken to us by His Son. This highlights that the ultimate revelation of God is found in Jesus Christ, who is not only the culmination of divine communication but also the embodiment of God's character. By examining the Old Testament, we see significant moments of God's presence and action, pointing to the eventual coming of Christ. These manifestations serve as a vital connection, illustrating how God's unchanging nature has been consistent throughout biblical history.
