What does the Bible say about the day of Jesus Christ's return?

Revelation 6:12-17 delineates the dramatic events that will occur on the day of Jesus Christ's return, including a great earthquake, the darkening of the sun, and the moon turning to blood. This day is marked as a time of unprecedented upheaval in the heavens and on earth, reflecting God's sovereign judgment against the wicked. It is known as the 'great day of the Lamb's wrath' and signifies the fulfillment of God's promises to avenge His people and execute justice upon those who oppose Him. As believers, we take comfort in knowing that this day will also bring our ultimate redemption and deliverance from the trials and tribulations of this world.
