We've heard how God was with the people of Judah during the exile. Now we turn to the end of the exile. King Cyrus of Persia (which took over the Babylonian Empire) received a revelation from God that he should let the people of Judah return home. The passage mentions this fulfills Jeremiah's prophecy, which stated that Judah would be in captivity for 70 years. If there was any doubt that God uses people who aren't part of the "right" religion, this passage clears that up. God can work through anyone, at any time. How will God work through you today?
