The Radiance of His Glory
When Heb 1:3 says He is the radiance of His glory and the exact representation of His nature, one thing it is saying is that Jesus never misrepresented the Father. That is why when Philip demanded, “Show us the Father” Jesus could say, “If you have seen me, you have seen the Father.”(Jn14:9) As the radiance of His glory Jesus did not glow but He lived out the character of God where it could be seen and benefited from. The character of the Father radiated out of the life that Jesus lived. That is the purpose of the Word of His power working mightily in us.
