Pastor Brian reminds us that we too can learn the same lessons as Zerubbabel. There is an inadequacy of strength and power from human flesh and a need of spiritual weapons. The Spirit of God is all-sufficient to complete the work of God. We can be assured that there will always be an unlimited supply of power for the work. No obstacle will be able to prevent the completion of God's work. And we can confidently remember that God delights in the work being done.
