What does it mean that Christ is the express image of God?

Hebrews 1:3 teaches that Jesus is the express image of His person, indicating that He fully reveals the nature and character of God. In Christ, we see the fullness of God expressed in human form, as He embodies both the character and the divine attributes of God. This truth affirms that to know Christ is to know the Father, as He clearly stated in John 14:9, 'He that hath seen me hath seen the Father.' Consequently, understanding Christ as the image of God emphasizes His divinity and authority, demonstrating that He is truly God incarnate, who holds all wisdom and power.
