Luke 5:25

And immediately he rose up before them, and took up that whereon he lay, and departed to his house, glorifying God.

Thus, a second time in this chapter, Jesus directed the most visible and convincing proof of his oneness with the Father toward the community of scribes and Pharisees, making every effort to enlist them as believers in his holy mission. From John it is learned, however, that they had already rejected him and were merely stalking him with a view of putting him to death (John 5:18). That prior evil decision on their part was the true reason why they did not believe in this circumstance.

Glorifying God ... The healed man was aware that only God could have wrought such a wonder; and the same conclusion should have been made by Jesus' enemies.
