He's coming literally. That means it's real. No imagination is required. It's an actual event occurring at a precise moment in time. The angel’s verified it when they said in Acts 1:11, “… this same Jesus which is taken up from you into heaven, shall so come in like manner as ye have seen him go into heaven."
He's coming personally. Jesus Himself promised that in John 14:3 “… I will come again, and receive you unto myself: that where I am, there ye may be also."
