In this passage, we see the glory of Jesus Christ in being the goal of our witness, the initiator of our salvation, the One with absolute authority to change our identity and command our allegiance, and the One who knows all things about us yet continues to love us. Ultimately, we see the "glory as of the only Son from the Father" in Jesus Christ's death on the cross. May we come and see, and then may we go and tell of His glory.
After concluding his theologically rich prologue, the apostle John turns his attention to the witness of John the Baptist. Rather than focusing on who he is and what he has done, John the Baptist focuses on who Christ is (the Lamb of God) and what Christ came to do (take away the sin of the world). The question is whether or not we are going to listen to the message of the messenger.
In this passage, John is stating very carefully and very deliberately that the Word, Jesus Christ, is eternally pre-existent, that He is in eternal relationship with the Father, that He is eternally God, and that He is the eternal Creator of all things. May we marvel at the majesty and splendor and wonder of Jesus Christ.
