The phrase refers to extraordinary celestial events and phenomena described in biblical texts that are interpreted as having symbolic or prophetic significance. These occurrences often involve alterations in the sun, moon, and stars, or the appearance of unusual atmospheric displays, understood within a religious framework as communicating divine messages or portending future events. A notable example can be found in the book of Revelation, which details dramatic astronomical disturbances associated with the end times.
Historically, such interpretations have provided believers with a sense of understanding and direction during times of uncertainty or societal upheaval. The perceived correspondence between terrestrial events and celestial anomalies strengthens faith and offers a framework for interpreting the world through a religious lens. The study of these perceived connections has influenced theological discussions and eschatological beliefs across various Christian denominations.
