Luke 10:21-24 is the only place in the Gospels where Jesus is described as rejoicing, so this message includes some discussion of Jesus' joy and then explores the reasons why He was rejoicing:
1. Reasons Jesus rejoiced:
Because God is sovereign over who gets saved (v21-22).
Because salvation is for unintelligent people (v21).
2. Reasons we should rejoice:
Because Christ has all the resources we need (v22).
Because truth is now much clearer (v23-24).
