The sermon this Sunday is on the final verse of the Prologue. The Incarnate Christ has made the invisible God known. The God-man Jesus Christ reveals the truth of God for all the world, vividly, personally, in history. No longer are we in the dark concerning God. To have seen Christ is to have seen the Father. With the incarnation of the Son of God, we have a sturdy and trustworthy rock of divine revelation upon which we can build our lives.
