Scripture is neither vague nor equivocal on the promise of Christ's return. A large portion (by some accounts, as much as one-fifth) of Scripture is prophetic, and perhaps a third or more of the prophetic passages refer to the Second Coming of Christ or events related to it. It is undeniably a major theme in the prophecy of both Old and New Testaments.
And regardless of what the scoffers say, Jesus is coming (2 Peter 3:3-10). World history is barreling toward the conclusion that God ordained. It isn't an end that will come as a result of nuclear war, environmental irresponsibility, or alien invasion; it is the one that comes by the purpose and plan of God, foretold in Scripture. Make no mistake--Christ will return!
Here are nine reasons from Scripture by which you can know that Christ is coming again.
The Promise of God Demands It
The Old Testament is full of Messianic promise--that promised is its main focus. From beginning (Genesis 3:15) to end (Malachi 4:2), the entire Old Testament is filled with prophecies of the coming Deliverer--at least 333 distinct promises, by one count.
Of the more than 100 prophecies dealing with the first advent of Christ, all of them were fulfilled precisely, literally. His riding on a donkey, the parting of his garments, the piercing of His hands and feet, and the vivid prophecies of His rejection by men in Isaiah 53--all these might have been interpreted symbolically by Old Testament scholars before Christ. But the New Testament record repeatedly reports that such things were fulfilled in the most literal sense, so "that the Scriptures of the prophets might be fulfilled" (Matthew 26:56; cf. 2:15; 4:14-16; 8:17; 12:17-21; 13:35; 21:4-5; 27:35; John 12:38; 15:25; 19:24, 28).
