Isaiah 40:9-10, “Go on up to a high mountain, O Zion, herald of good news; lift up your voice with strength, O Jerusalem, herald of good news; lift it up, fear not; say to the cities of Judah, “Behold your God!” 10 Behold, the Lord GOD comes with might, and his arm rules for him; behold, his reward is with him, and his recompense before him.”
“I just want to shout it from the rooftop!” An exclamation likely felt and perhaps made by many a young lad or lass smitten with keen affection. So full of joy and love they want everyone to know. But here the prophet speaks to Jerusalem itself, that is to the people of God, and reminds us that we have a joy far greater and deeper, which ought to be shouted from the highest of mountains. And the joy is this “Behold your God!” That is essentially the Christmas message. That God can be beheld. That He who dwells in unapproachable light, who could only allow Moses, himself the pinnacle of human piety, to see his back, can now be seen plainly by all. God can be beheld in the face of Jesus Christ. And He has come to reign. Jesus is the might of God. He is His holy right arm. He is the reward of those who trust in Him. And He brings the recompense for the enemies of God’s people. He brings death for death and destruction for sin and hell. He brings everlasting joy for you. Go tell it on the mountain! For behold! Your God is here.
