Salvation's Triumph
The main idea in verses 4-11 of chapter 61 is that we are to produce the fruit of righteousness, praising God for His salvation in Christ. The work of Christ is to transform and restore God’s creation. He is sent to bring righteousness and praise among God’s elect. Jesus is sent to us. He intervenes in our life and establishes us as oaks of righteousness. We are to produce the fruit of righteousness as a result of Jesus being sent.
City of the Lord
The work of the Messiah is transforming. Isaiah prophecies that God will transform deserts into lush gardens. Animals have a new nature so that the lion lays down with the lamb. And, God will transform people so that they are no longer rebellious, but righteous and holy. Isaiah 60, and Revelation 21 are passages prophesying that God will transform Jerusalem into a glorious city. She will be a sparkling gem upon the earth.
Righteous City
The main idea of this passage is very simple. We are to worship the Savior for His remarkable transforming work of deliverance. To truly worship Jesus, others will see Him as being the center of our heart and affections. His name is on our lips. His salvation dominates our conversations. When we worship Jesus, the church is a sparkling jeweled city where we grow in the knowledge of Christ and learn how Jesus is to be the center of our life.
