Today's Liturgy of the Word represents a kind of wrap-up to the lives of St. Paul and Jesus, respectively. They both have completed the mission for which they had been sent, and both are now giving the mission back to God who would continue it as He alone saw fit. Paul's mission had been one of conversion, beginning with his own, and then reaching out to the Gentiles he met traveling far and wide. Now he did not know what would happen to him, only that the Holy Spirit kept telling him it was to be an end filled with hardship, from which Paul refused to shrink.
Jesus, one with the Father from the beginning, had come from the Father and was now going back to the Father. He brought God's love to bear on the aberrations of sin and death and had drawn disciples into the mission to continue the work. It could not continue unless he returned to the Father and sent the Holy Spirit upon them. Doing that has brought the Gospel into every nation and into the lives of millions. He too faced an end filled with hardship, from which he refused to shrink.
We disciples will come to our own ends as well. Will we too be able to give the mission back to the Father, confident that we've done it as best we could, and confident that it would be continued as God saw fit? Have our days sometimes been filled with hardship, and if so, have we also refused to shrink from it? We disciples are part of the mission that God has in the world. We take it for a time and will eventually have to hand it back over. May we all be able to do so with confidence that God's will has been done in us.
