It's God's Work -- "...all our concern and worrying will not change a thing."

It is not ours but our great God and Savior's own work that is carried out among us. If it stands, it stands for him. If it fails, it falls for him. If it stands, the gates of hell shall not overcome it. Should it fall, we will not be able to preserve it. All our racing and running, all our concern and worrying will not change a thing. Therefore we cast all our cares upon him (I Peter 5:7). Care and worry is his affair. Our matter is that we, as faithful servants, each do and perform his mandated office and work so long as it is day. So let us have courage to continue to build and to be faithful...
