"And I saw heaven opened, & behold, a white horse, & He who sat on it is called Faithful & True; & in righteousness He judges & wages war. And His eyes are a
flame of fire, & upon His head are many diadems; & He has a name written upon
Him which no one knows except Himself. And He is clothed with a robe dipped in blood; & His name is called the Word of God." [ Rev.19:11-13 ]
Jesus said to His disciples, "Let let not your heart be troubled; believe in God, believe also in Me. In My Father's house are many mansions; if it were not so, I would have told you; for I go & prepare a place for you. And if I go & prepare a place for you, I will come again, & receive you unto Myself; that where I am, there you may be also." (John 14:1-3).

Scriptures are clear that Christ's 2nd appearance to the world will be His literal physical return back to earth. His return will take place on the very last day of the 7 year tribulation, in order to inter- vene & stop the antichrist's efforts to destroy all of the human race.
