The “…ends of the world…” (1 Corinthians 10:11) is the ending and transitional period of the world as we know it. It is called, “…the great day of Jehovah…” (Zephaniah 1:14 YLT). The righteous Kingdom of God, under the authority of Christ, will be gradually established on earth as the unjust governments and systems of the present world pass away. Isaiah 61:2 lists this period as, “…the day of vengeance of our God…". Psalm 110:5 describes this as "…the day of His wrath." Daniel 7:9, 13, & 14 (KJV) states, “…the thrones were cast down, and the Ancient of days did sit…and behold, one like the Son of man came…And there was given him dominion, and glory, and a kingdom, that all people…should serve him: his dominion is an everlasting dominion, which shall not pass away…shall not be destroyed.”
Various prophecies describe this ending period of the old evil world order. It overlaps with transitional events required to fulfill the promise in Acts 3:21 (NIV), “…for God to restore everything, as he promised long ago through his holy prophets.”
There is a prophecy detailing the fall of false Christian systems. These systems are Christian in name only (meaning not true at heart, not holy spirit-begotten, unfaithful). Revelation 18:21 prophesies, “And a mighty angel took up a stone like a great millstone, and cast it into the sea, saying, Thus with violence shall that great city Babylon be thrown down, and shall be found no more at all.” As the literal Babylon fell to ruin, so symbolic Babylon (nominal Christianity) will fall. It will be raised as though it were a giant stone. Then its sudden, violent fall will bring total destruction of its unjust practices. This will forever be a forceful example of why and how God will eliminate all hypocritical systems.
The prophecy describing future mourning of those responsible for Jesus’ death is found in Zechariah 12:10. “…and they shall look upon me whom they have pierced, and they shall mourn for him, as one mourns for his only son, and shall be in bitterness for him, as…for his firstborn.” When Jesus, our Lord and redeemer, awakens ALL mankind (John 5:28,29), people will be taught God’s plan and instructed in righteousness (Hebrews 10:16). They will know that Jesus is “…a ransom for all…” 1 Timothy 2:6.
The Bible describes the end of the world as a time when Christ removes all manmade, unrighteous systems. Temporary, severe upheaval will lead to the fulfillment of God’s wonderful promise for mankind found in Revelation 21:4. ”…God shall wipe away every tear from their eyes…death shall not be any more, nor sorrow, nor crying, nor…pain, because the first things did go away.” (YLT).
