When the crowd saw it, they were amazed. They were glorifying God, who had given such authority to people.
In this passage, when the people saw the miracle Jesus performed, they were amazed and glorified God. They understood that such authority, which included the ability to forgive sins and to bring physical healing, God had given through a man—in this case, Jesus Christ. The crowd realized that this kind of authority is unique and surpasses human ability, and therefore they directed their praise to God, with the awareness that Jesus acts by God’s power.
