Lightning flashes across the sky
East to West, do or die
Jesus: ​​“For as the lightning flashes across the sky from east to west, so shall my coming be, when I, the Messiah, return.” Matthew 24:27 TLB
Like a thief in the night
​See the world by candlelight
For you yourselves know full well that the day of the Lord will come just like a thief in the night. 1 Thessalonians 5:2 NASB

But the day of the Lord will come as a thief in the night; in the which the heavens shall pass away with a great noise, and the elements shall melt with fervent heat, the earth also and the works that are therein shall be burned up. 2 Peter 3:10 KJV
