Let not your heart be troubled: you believe in God, believe also in me.
All Commentaries on John 14:1 Go To John 14
Augustine of Hippo
AD 430
Our Lord consoles His disciples, who, as men, would be naturally alarmed and troubled at the idea of His death, by assuring them of His divinity: Let not your heart be troubled: you believe in God, believe also in Me; as if they must believe in Him, if they believed in God; which would not follow, unless Christ were God. you are in fear for this form of a servant; let not your heart be troubled; the form of God shall raise it up.
And as the disciples were afraid for themselves, when Peter, the boldest and most zealous of them, had been told, The cock shall not crow, till you have denied Me thrice, He adds, In My Father's house are many mansions, by way of an assurance to them in their trouble, that they might with confidence and certainty look forward, after all their trials, to dwelling together with Christ in the presence of God. For though one man is bolder, wiser, juster, holier than another, yet no one shall be removed from that house of God, but each receive a mansion suited to his deserts. The penny indeed which the householder paid to the laborers who worked in his vineyard, was the same to all; for life eternal, which this penny signifies, is of the same duration to all. But there may be many mansions, many degrees of dignity, in that life, corresponding to people’s deserts.
And thus God will be all in all; that is, since God is love, love will bring it to pass, that what each has, will be common to all. That which one loves in another is one’s own, though one have it not one’s self. And then there will be no envy et superior grace, for in all hearts will reign the unity of love.
But they are rejected by the Christians, who infer from there being many mansions that there is a place outside the kingdom of heaven, where innocent souls, that have departed this life without baptism, and could not there enter into the kingdom of heaven, remain happy. But God forbid, that when every house of every heir of the kingdom is in the kingdom, there should be a part of the regal house itself not in the kingdom. Our Lord does not say, In eternal bliss are many mansions, but they are in My Father’s house.
He means evidently that there are already many mansions, and that there is no need of His preparing one.
But why does He go and prepare a place, if there are many mansions already? Because these are not as yet so prepared as they will be. The same mansions that He has prepared by predestination, He prepares by operation. They are prepared already in respect of predestination; if they were not, He would have said, I will goand prepare, i.e. predestine, a place for you; but inasmuch as they are not yet prepared in respect of operation, He says, And if I go and prepare a place for you. And now He is preparing mansions, by preparing occupants for them. Indeed, when He says, In My Father's house are many mansions, what think we the house of God to be but the temple of God, of which the Apostle said, The temple of God is holy, which temple you are (1 Cor 3:17). This house of God then is now being built, now being prepared. But why has He gone away to prepare it, if it is ourselves that He prepares: if He leaves us, how can He prepare us? The meaning is, that, in order that those mansions may be prepared, the just must live by faith and if you see, there is no faith. Let Him go away then, that He be not seen; let Him be hid, that He be believed. Then a place is prepared, if you live by faith: let faith desire, that desire may enjoy. If you rightly understands Him, He never leaves either the place He came from, or that He goes from. He goes, when He withdraws from sight, He comes, when He appears. But except He remain in power, that we may grow in goodness, no place of happiness will be prepared for us.
