There are three main themes in this passage; three key features of the path of peace. First, love for Jesus always equals obedience to Jesus. Second, when Jesus returned to the Father, He sent the Holy Spirit to help His followers. And third, Jesus' followers will experience Jesus' resurrection life. Combined, they give us the big idea of the passage: Jesus' love for His people led Him to the cross and to provide for them once He was gone. And from that, our main takeaways are to love and obey Jesus, to walk in the Spirit's power, and to live in light of the fact that it is not death to die.
