“And now come I to thee; and these things I speak in the world, that they might have my joy fulfilled in themselves.”
John 17:13 — Greek Interlinear
Church Fathers on John 17:13
As the disciples were still sad in spite of all our Lord’s consolations, henceforth He addresses Himself to the Father to show the love which He had for them; I pray for them; He not only gives them what He has of His own, but entreats another for them, as a still further proof of His love.
When He adds, I pray not for the world, by the world He means those who live according to the lust of the world, and have not the lot to be chosen by grace out of the world, as those had for whom He prayed: But for them which you have given Me. It was because the Father had given Him them, that they did not belong to the world. Nor yet had the Father, in giving them to the Son, lost what He had given: For they are Yours.
