Don’t Worry He’s Sovereign: Unleavened Bread (Mark 14:12-26)

I wonder what it must have been like for the disciples to have the last supper with Jesus.  They would expect this to be a normal day where they could enjoy the day and the time with one another recounting the history of Israel.  Their experience is something that is radically different as Christ is preparing them for what awaits Him in His ministry: His betrayal and death.  The disciples are horrified, and so what is the assurance in this text that there is no need to worry?  How do we know that Christ is still in control?
