At the center of the Christmas event is the monumental mystery of God becoming man. The mere statement of this must send our minds into great wonder. How could an uncontainable, spiritual being ever become contained in flesh and time? How could the Maker of all take on the image of one made? And to what purpose?
John wrestled with all of these questions and came out a solid proclaimer and defender of the simple truth that Jesus Christ was, indeed, fully divine and fully human. He was the God-Man, and His incarnational mission could only be accomplished by One who was uniquely God and man.
John reaches back to the Old Testament book of Exodus to discuss the fact that the Word became flesh and dwelt among men. In so doing, he both proves his point and grounds the coming of God in the flesh in the great history of God’s redemptive plan. The incarnation wasn’t an accident. Before time began it was determined that the sin of mankind could only be remedied through the humiliation of the incarnation. And yet, in the midst of His time on earth, Jesus demonstrated the glory of God, full of grace and truth.
