Matthew cites a profound reason as to why the crowds glorified God in Matthew 9:8. After Jesus tells a paralytic that his sins are forgiven, he proves it by healing the man. The text then says in verse 8:
But when the crowds saw this, they were awestruck, and glorified God, who had given such authority to men.
The overarching story of the Bible has many themes, structures, and beats, and one of them about God gradually entrusting man with more and more authority and responsibility. Man is initially given dominion over the whole earth and the things therein. After the flood, man gets authority to judge capital crimes, representing authority over his fellow man (Gen. 9:5-7). With post-Exodus Israel, we see men given the responsibility to guard and serve God’s throne-room sanctuary. With Solomon, we see a man given the ability to discern between good and evil, granting as a gift what Adam had prematurely seized in the garden (1 Kings 3:9).
With Jesus, we see this theme reach its climax. It is a big deal that a man has the authority to forgive sins. The Son of Man, our brother, has been invested with this authority. And it is also the climax of this particular section of Matthew. The end of chapter 7 until 9:8 is all about authority.
The crowds were amazed at his teaching, because he taught as one having authority. (7:29)
The centurion says that he too is a man under authority, comparing himself to Jesus, and that servants and soldiers under him “go” and “come” according to his command. (8:5-9)
Then we get the scene that seems like the climax, the height of Jesus’ authority, when he calms the storm. The disciples marvel at “what kind of man is this, that even the winds and the sea obey him?” (8:27) What could be greater than this? Our jaws drop along with the disciples.
But that is not the end nor the pinnacle of this section, as we soon learn. The only place where people glorify God is after Jesus says he has the authority to forgive sins. That is when he is at his most powerful. Cleaning the slate, reconciling people to a holy, righteous God.
And that power is invested in a man.
Yet another thing to add to the wonder of the Incarnation.
