How does Psalm 68:1 connect to Stephen's speech about Jesus?
Psalm 68:1 calls for God to arise and scatter His enemies. In Stephen's speech, this pictured Jesus having risen from His seated position and being ready to come, so the psalm's language connects to Christ's exaltation and impending return.
Les explains that after Psalm 67's kingdom promises, Psalm 68:1 says, "Let God arise, let His enemies be scattered." He notes God the Son is God just as much as God the Father and God the Spirit. This verse, Les says, is what Stephen was talking about: Jesus had now arisen from His seated position and was ready to come. The next verses describe enemies driven away like smoke and the wicked perishing before God. Israel knew they were not ready for that, and rather than bringing conviction and godly fear, it aroused their anger. Les then directs listeners back to Acts chapter 7.
Let God arise, let his enemies be scattered: let them also that hate him flee before him.
