John 17:6

From praying for Himself He now comes to pray for His disciples. I have manifested--I manifested. thy name--His whole character towards mankind. to the men thou gavest me out of the world--(See on Joh 6:37-40).

Christ, having prayed for himself, comes next to pray for those that are his, and he knew them by name, though he did not here name them. Now observe here, I. Whom he did not pray for (Joh 17:9): I pray not for the world. Note, There is a world of people that Jesus Christ did not pray for.

These are called the world, because they are governed by the spirit of this world, and have their portion in it; for these Christ does not pray; not but that there are some things which he intercedes with God for on their behalf, as the dresser for the reprieve of the barren tree; but he does not pray for them in this prayer, that have not part nor lot in the blessings here prayed for. He does not say, I pray against the world, as Elias made intercession against Israel; but, I pray not for them, I pass them by, and leave them to themselves; they are not written in the Lamb's book of life, and therefore not in the breast-plate of the great high-priest. And miserable is the condition of such, as it was of those whom the prophet was forbidden to pray for, and more so, Jer…

17:6 This verse summarizes Christ’s mission. He revealed the true person of God to the world, gathered up God’s people into his flock, and instructed them in obedience. The result of this work is the church.
