1. Miracles only occurred during the time of the Bible, so we should not expect them in modern times. A: "Minister, in the Bible, Moses could part the seas with his staff and people were often saved from certain death. Why doesn't that happen anymore?" B: "Well, the age of miracles is past. God has arranged it now that such things shall no longer occur until the day of Judgment."

2. Said more generally when facing or discussing some impossible, or seemingly impossible, task or situation. It would take near-total bipartisan support for the bill to make its way through both houses of Congress, and the age of miracles is past. Sorry, the age of miracles is past—there's no way we're getting your car up and running again.
