And if I go and prepare a place for you, I will come again, and receive you unto myself; that where I am, there ye may be also.
This refers to the time when Jesus will come back again in the air, when those who have died in faith will be raised, when the living will be changed, and when all the blood-bought individuals will be taken home to heaven. This is a personal, literal coming of Christ. As surely as He went away, Christ will come again. Our blessing is that Jesus desires for us to spend eternity with Him.
