“At that time the sign of the Son of Man will appear in the sky, and all the nations of the earth will mourn. They will see the Son of Man coming on the clouds of the sky, with power and great glory” (Matthew 24:30).
This verse describes the literal return of Christ to the earth. The people of the earth will mourn when they see Christ returning because 1) they know he is coming in judgment, and 2) they will realize they are not ready for his coming. This will be a sign visible to the entire earth. “Behold, he is coming with the clouds, and every eye will see him, even those who pierced him, and all tribes of the earth will wail on account of him” (Revelation 1:7 ESV).
The Second Coming of Christ will be “with power and great glory.” Perhaps the best way to understand that statement is to compare the circumstances surrounding the first and second comings. 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. In his first coming he endured the mockery of men who despised him for his goodness. 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. He came the first time as the Lamb of God; he comes again as the Lion of the Tribe of Judah. Two thousand years ago the religious leaders shouted in scorn, “He saved others, but he can’t save himself!” (Matthew 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 (Philippians 2:9-11)
Around the first coming inscribe the word HUMILTY in letters large and bold. Around His second coming inscribe the word GLORY so that all the world may see. Nothing could be more natural than a triumphant return of our victorious Lord. Though He was once “despised and rejected of men,” He will one day return “in power and great glory,” heralded by angels and accompanied by his saints.
