The first coming of Christ was a veiled coming. Wesley got it right in that magnificent hymn: “Veiled in flesh the Godhead see, Hail the incarnate Deity.” His glory, His majesty, was veiled. The next time He comes, it will be unveiled. The first time He came, His glory was veiled. The second time He comes, His humanity will be veiled. The first time He came, His humanity was on display for all to see, and that is all that most people ever saw. There were only three people who ever saw His glory on the Mount of Transfiguration. Just three: Peter, James, and John. The rest of the world saw only His humanity. The next time He comes, the whole world will see His glory. His humanity will be hidden.
To really understand who Jesus Christ is, you have to see Him unveiled, and the best place to see Him unveiled is in the apocalypse, the unveiling. So, open your Bible to the Book of Revelation. And throughout the Book of Revelation, there are titles, and there are statements made concerning Christ that take the veil off and reveal who He really is. Not just a baby in a manger. That becomes very clear in the Book of Revelation when we see Him in His unveiled glory.
