“In my Father's house are many mansions: if it were not so, I would have told you. I go to prepare a place for you.” (John 14:2)
Where was Jesus going? To Calvary! Of course He was going to Heaven, but Calvary was where he provided a mansion for us. You see, the mansions already exist (v. 2 speaks of present tense), they are already waiting for us, and only God knows the number of them. A virtual Holy city--a city full of individual mansions, which are the proper dwelling for royalty! Jesus, in all actuality, prepared us for the mansion--He prepared a place for us in a mansion in Heaven. We must meet Him at Calvary first though before we can meet Him in Heaven; this refers us back to verse one: “Let not your heart be troubled: ye believe in God, believe also in me.” That is How we meet Jesus at Calvary. Until Christ died on the cross, we had no place in Heaven--no eternal life; Jesus had to go and prepare the way for us, and He is the Way; the “preparation“ is Calvary. (John 14:6).
If He goes (and He did go) he will doubtless come again to deliver us to our mansion--to take us to heaven to be with Him (v.3). The way has been prepared already. We know the way; we know that it is through Jesus that we will go to heaven and receive our mansion, because He is “the Way, the Truth, and the Life: no man cometh unto the Father” but by Him (v. 6).
