The Bible speaks of the end times in books like Revelation, Matthew, and Joel, describing a dark sky and a red moon rather than a "blood red sun." The moon turning to blood is a classic sign of the end of days before the great day of the Lord arrives. Joel 2:31: The sun turns to darkness and the moon to blood before the day of the Lord comes.Revelation 6:12: The sun becomes black like sackcloth and the full moon becomes like blood.Matthew 24:29: The sun is darkened and the moon will not give its light after the tribulation of those days. Poetic phrasing: "Blood red sun" is a popular phrase in modern poems, music, and art rather than a direct Bible quote.Prophecy meaning: These signs show major changes in nature and the power of God during judgment.Book of Isaiah and Matthew: Similar cosmic disruptions and darkened lights are mentioned in Isaiah 13:10 and Matthew 24:29 regarding judgment and the return of Christ.Book of Revelation (Revelation 6:12): Describes the sun turning black as sackcloth and the full moon turning red like blood when the sixth seal is opened. Book of Acts (Acts 2:20): The Apostle Peter quotes Joel's prophecy during Pentecost as a sign from God.Signs of Judgment: These sky events show God's power over creation and mark moments of divine judgment on the world.The Day of the Lord: They act as visible warnings that a major, holy turning point in human history is near.
