Matthew 16:21
21From that time, Jesus began to show his disciples that he must go to Jerusalem and suffer many things from the elders, chief priests, and scribes, and be killed, and the third day be raised up.
“Must” is the grammar of saving love: the cross is necessary, not accidental. Messiah’s path runs through suffering to resurrection.
This death is sufficient for the world and sincerely offered in the preaching of Christ crucified. Grace calls all to trust the risen Lord.
From this hinge (“from that time”) Jesus unfolds the decree-shaped path: suffer, be killed, be raised. The cross is not Plan B.
He dies for His people according to the Scriptures, and the third-day rising is as certain as the suffering. Providence and promise hold both.
