How awesome and inspiring this is! Christ Jesus is the image of the invisible God. Now, that word "image" is the Greek "eikon," which is translated 'icon" in English. Think about a computer or a mobile device, for example. You may not see the application in the system, but you see the icon—a quickly comprehensible symbol—that helps to easily navigate that computer system or mobile device as you click on it.
Colossians 1:15 tells us that Jesus "...is the image of the invisible God, the firstborn of every creature"; that means He's the outward expression of the invisible God. To see Jesus, is to see God. In John 14:8-9, when Philip asked, "...Lord, shew us the Father, and it sufficeth us," Jesus responded, "...he that hath seen me hath seen the Father; and how sayest thou then, Shew us the Father?"
Jesus is the perfect image and replica of the Godhead. He's the express image of the Father's person. The Father joyfully appointed Him to be the heir of all things, including His throne. The Bible says it pleased the Father, that in Him (Jesus) should all fullness dwell (Colossians 1:19).
Then Colossians 2:9 lets us know that in Him (Jesus) dwells the fullness of the Godhead bodily. So, if you've seen Jesus, you've seen the Father. Glory to God!
He said in John 10:30, "I and my Father are one." When He said this, the Jews, not knowing who He was, said He blasphemed and they attempted to stone Him to death: "Then the Jews took up stones again to stone him.
Jesus answered them, Many good works have I shewed you from my Father; for which of those works do ye stone me? The Jews answered him, saying, For a good work we stone thee not; but for blasphemy; and because that thou, being a man, makest thyself God" (John 10:31-33). They understood the implication of what He said. Jesus is one with the Father; He's the complete embodiment of Deity.
