The darkening of the sun, together with the moon turning to blood, belongs to the Sixth Seal and the day of the Lord (Joel 2:31; Revelation 6), not to the present time. These events come as part of a wider cosmic upheaval: the stars fall, the sky recedes, and the heavens and the earth are shaken. God tells Haggai twice that He will shake the heavens, Christ says the powers of the heavens will be shaken (Matthew 24:29), and Isaiah 13:13 says the earth will be moved out of its place. Because the heavens now move with clockwork stability, eclipses can be predicted centuries ahead. When the Sixth Seal opens, that stability is overturned, so even if eclipses are part of what happens, NASA will not be able to calculate them. The timing is also fixed. The Olivet Prophecy places the darkening of the sun, the moon withholding its light, and the falling of the stars after the great tribulation, which is unlike anything before it. The Sixth Seal follows the Fifth Seal, the martyrdom of those who hold God's testimony. Religious violence is increasing, but things have not reached the point where God must cut them short for the elect. It is still early to look for the sun's darkening, and a tetrad of lunar eclipses on the holy days does not match all that Scripture says about this event.

Scripture links the darkening of the sun, moon, and stars with times of judgment. The Sixth Seal of Revelation 6:12-14 includes that darkening as the beginning of God's judgment on those persecuting His people. Joel mentions it three times as a precursor to the wrath of the Day of the Lord (Joel 2:10, 31; 3:15). Isaiah 13:10 foretells the heavenly lights going dark in God's judgment on Babylon, and Ezekiel 32:7-8 ties the darkening of the heavens to God extinguishing the light of the whole nation of Egypt. Ecclesiastes 12 uses the same imagery for the dimming of a man's mind as he nears death. Light symbolizes understanding, life, and vitality, while darkness signifies incomprehension, confusion, and doom. In each case, the darkening marks the approaching end of a period of judgment, whether for a nation or a person. Genesis 1:14 says God set the lights in the firmament for signs and seasons, and the word for seasons (moedim) means appointed times or times of gathering, not summer and winter. When the lights God made to mark His times are darkened on those very times, such as the Feast days, the occurrence is an open invitation to consider what God may be doing. Solar and lunar eclipses falling on His appointed days, together with the year of release, seem beyond coincidence.

The darkening of the sun forms one element within the sixth seal's cluster of cosmic disturbances, described in Revelation 6:12-17 as occurring alongside a great earthquake, a moon turned to blood, falling stars, and a sky that recedes like a scroll. John describes the sun becoming black as sackcloth of hair, comparing it to the black goat hair used for tents and sackcloth in his day. This darkening may depict a solar eclipse or possibly a massive dust storm caused by volcanic explosion, and it parallels the thick darkness of the Ninth Plague on Egypt, which God may repeat on a grander scale. Whatever the specific cause, the result will be severely limited visibility even during daylight hours. This solar darkening is not an isolated phenomenon but part of a broader biblical pattern in which God uses aberrations in expected solar behavior to signal major movements in His plan, as seen in the Ninth Plague, Joshua's Long Day, Hezekiah's Sundial, and the darkness during Jesus' crucifixion. The sixth seal's darkening of the sun continues this pattern, and it is corroborated by other prophetic passages: Joel 2:30-31 foretells that the sun shall be turned into darkness before the great and terrible day of the Lord, and Jesus Himself repeats this warning in the Olivet Prophecy, stating that the sun will be darkened immediately after the tribulation of those days, with Luke's account adding that there will be signs in the sun causing distress among nations and hearts failing from fear. Within the sixth seal's structure, the darkened sun functions as one of several terrifying cosmic wonders that signal the beginning of the Day of the Lord while simultaneously serving as judgments against sinful mankind. These signs, occurring in tandem with a massive earthquake, produce such terror that people of every social rank—kings, great men, commanders, slaves, and free men—flee to caves and rocks, begging the mountains to fall on them and hide them from the face of God and the wrath of the Lamb. Remarkably, sinners correctly identify these catastrophic events as evidence of God's wrath rather than mere natural disaster, recognizing that such a succession of disturbances can be nothing other than divine anger. The darkening of the sun thus contributes to the overwhelming, undeniable announcement that the great day of the Lord has arrived, prompting the rhetorical question of Revelation 6:17: who is able to stand? The answer offered through Joel's prophecy and Jesus' own instruction in Luke 21:36 is that survival depends not on escaping the physical darkness but on watching, praying, and maintaining a strengthened relationship with God through obedience, seeking His face before the day of wrath arrives.
