"He is the radiance of His glory and the exact representation of His nature" (Heb. 1:3).
Jesus is both God manifest and God in substance.
Just as the rays of the sun give light, warmth, life, and growth to the earth, so Jesus Christ is the glorious light of God shining into the hearts of men and women. As "the radiance of God's glory," Jesus expresses God to us. No one can see God in HIs full glory; no one ever will. The radiance of that glory that reaches us from God appears in the Person of Jesus Christ.
Just as the sun was never without and can never be separated from its brightness, so God was never without and cannot be separated from the glory of Christ. Never was God without Him or He without God, and never in any way can He be separated from God. Yet the brightness of the sun is not the sun, and neither is Jesus exactly the same as God in that sense. He is fully and absolutely God, yet as a distinct Person within the triune Godhead.
Jesus said, "I am the light of the world; he who follows Me shall not walk in the darkness, but shall have the light of life" (John 8:12). As the radiance of God's glory, Christ can transmit that light into your life and mine so that we can radiate the glory of God to a dark world.
In using the term "exact representation" to describe Christ's relationship to God's nature, the writer employs terminology usually associated with an impression reproduced on a seal by a die or stamp. Jesus Christ is the reproduction of God—the perfect, personal imprint of God in time and space.
How wonderful to realize that Jesus Christ, who is both the full expression of God and exact reproduction of God's nature in human history, can come into our lives and give us light to see and to know God! His light is the source of our spiritual life. And His light gives us purpose, meaning, happiness, peace, joy, fellowship, everything—for all eternity.
