What does the Bible say about Christ being the messenger and the message?

In Hebrews 1:1-2, it is affirmed that God communicated in various ways through the prophets in the past but has spoken definitively through His Son in these last days. Jesus Christ is not merely a messenger; He embodies the message of God's redemptive plan. Through His life, death, and resurrection, He fulfills the promises made in the Old Testament and reveals the fullness of God's grace and truth. Thus, understanding Christ as both the messenger and the message is crucial to grasping the entirety of scripture and God's plan for salvation.
