God is promising the Israelites life after the return from exile. God will refresh the weary and satisfy the faint. He promises renewal after living in Babylon.
God is promising that he will surely build and plant again as he had uprooted and torn down before. He promises to make a new covenant with the people of Isarel.
Through this new covenant, God will put his law in the people's mind and write it on their hearts. Through this new covenant, God will forgive all their sins and wickedness. The new city that God will build will never be uprooted or demolished again.
We suffer and are sometimes punished due to our sins. Yet God is promising the renewal and rebuilding of our lives. God is promising us the new covenant, which was fulfilled through Jesus Christ. In Jesus, we are rebuilt, satisfied, and refreshed. Through Jesus, we have God's law in our hearts. Through Jesus's death on the cross, we are forgiven. God is promising us the new city, the kingdom of heaven, to those who are renewed through Jesus Christ.
Application: Lord, help us to receive the new covenant in Jesus Christ and be renewed.
One Word: Jesus is the new covenant
