There is never going to be world peace on this earth. “For when they shall say, peace and safety; then sudden destruction cometh upon them, as travail upon a woman with child; and they shall not escape” (1 Thessalonians 5:3).
“Seeing then that all these things shall be dissolved, what manner of persons ought ye to be in all holy conversation and godliness, looking for and hasting unto the coming of the day of God, wherein the heavens being on fire shall be dissolved, and the elements shall melt with fervent heat?” (2 Peter 3:11-12).
“Nevertheless we, according to his promise, look for new heavens and a new earth, wherein dwelleth righteousness” (2 Peter 3:13).
Jesus says: “Watch ye therefore, and pray always, that ye may be accounted worthy to escape all these things that shall come to pass, and to stand before the Son of man” (Luke 21:34–36).
