When they saw Him, they worshiped Him; but some were doubtful. 18: And Jesus came up and spoke to them, saying, “All authority has been given to Me in heaven and on earth.
Christ is more particular here in foretelling his sufferings than before. And here, as before, he adds the mention of his resurrection and his glory, to that of his death and sufferings, to encourage his disciples, and comfort them. A believing view of our once crucified and now glorified Redeemer, is good to humble a proud, self-justifying disposition. When we consider the need of the humiliation and sufferings of the Son of God, in order for the salvation of perishing sinners, surely we must be aware of the freeness and richness of Divine grace in our salvation.
Matthew Henry’s Commentary
