The verse takes a surprising turn, revealing God's active involvement even with those who don't acknowledge Him. How can this be?
The latter part of Isaiah 45:5 presents a profound truth about God's providential rule over all creation:
Divine Provision for the Ignorant
"I equip you, though you do not know me." This is directed at Cyrus, the Persian king who would be instrumental in the Israelites' return from exile. He is presented as a tool in God's hand, empowered and prepared for his task, despite his pagan beliefs.
The Sovereign Hand in History
Commentators note that "girded" refers to being prepared, strengthened, and equipped for action, much like a soldier putting on a military belt. God is the one who provides this strength and capability. This doesn't mean God endorses Cyrus's idolatry, but rather that He sovereignly uses even those who don't know Him to accomplish His purposes. This highlights God's ultimate control over all human affairs and history.
