And still our General, who never makes a mistake, says to us, “Advance; enter new territory; lift the standard in every land. ‘Arise, shine; for thy light is come, and the glory of the Lord is risen upon thee.’ [ Isaiah 60:1 .]” GW 470.1"
"Arise, shine; for thy light is come, and the glory of the Lord is risen upon thee."
