The Old Testament tells us that He will come. The Four Gospels tell us that He has come. From the book of Acts through the book of Revelation we read that He will come again.
The first time Jesus came unnoticed into the world, the second time “every eye will see Him.”
In His first coming Jesus humbled Himself, being born in a stable in Bethlehem. When He returns, He will come back as King of Kings and Lord of Lords.
The first time the antichrist Herod sought to kill the Christ Child to prevent Him from becoming King causing Him to flee to Egypt. When Christ returns as King He will cast the Antichrist into the Lake of Fire.
He came the first time as the Lamb of God; He comes again as the Lion of the Tribe of Judah.
In His first coming he endured the mockery of men who despised Him for His goodness and mercy. Although He was the Son of God, He allowed them to put Him to death, that He might thereby provide salvation for the world. When He comes again, all mockery will cease for He will rule the nations with a rod of iron.
Two thousand years ago the religious leaders shouted in scorn, “He saved others, but He can’t save Himself!” (Matt. 24:42). The day is coming when the whole world will see Jesus as He really is. When that happens, "every knee will bow and every tongue confess that Jesus Christ is Lord, to the glory of God the Father" (Philip. 2:9-11).
The first time the disciples of John the Baptist asked: “Are you he who is to come, or shall we look for another?” And Jesus answered them, “Go and tell John what you hear and see: the blind receive their sight and the lame walk, lepers are cleansed and the deaf hear, the dead are raised up and the poor have good news preached to them” (Matt. 11:3-6).
When Jesus comes again the following words will be fulfilled: "Behold, the dwelling of God is with men. He will dwell with them, and they shall be His people, and God himself will be with them; He will wipe away every tear from their eyes, and death shall be no more, neither shall there be mourning nor crying nor pain anymore, for the former things have passed away” (Rev. 21:3-4).
