The sermon title seems to send a mixed message: how is it possible that Palm Branches of Joy are mixed with Grapes of Wrath? It’s not a mixed message; it’s an indication there are two different messages that are very much connected. One message is of ultimate Triumph, of a victory that is unassailable. The other message is of a final Judgment that is eternal. Luke’s record of the events of Palm Sunday includes an incident rarely read with the other events of that day. His record is a harbinger of events Revelation 14 will describe in more prophetic, agonizing detail.
