Why is Jesus referred to as the Word of God?

The title 'Word of God' signifies that Jesus is the ultimate expression of God's character and will. As stated in John 1:1, He was in the beginning with God, and He is God. This reveals that Jesus embodies not just the spoken Word but the essence of God's communication to mankind. In Him, all mysteries of wisdom and knowledge are encapsulated. He is God's final revelation, fulfilling and surpassing the previous revelations through the prophets. Thus, understanding Jesus as the Word is crucial for grasping the entirety of God's message to humanity.
