The  Gospel is from St. Matthew 10:37-42. In the first part, Christ tells his representatives, his delegates the Apostles, and those who succeed them, that they must be prepared to undergo great sacrifices, even death itself, if called on to do so for the sake of Christ.  
It was not only the Apostles who gave their lives gladly for Christ. There are thousands of martyrs who, during the first three centuries of the Church, not only accepted but welcomed death for Christ's sake, because they were convinced that it was the door to eternal life, the only life that mattered. Nor did occasions for martyrdom cease when the Church was granted freedom by Constantine, the first convert Roman emperor. Here and there, down through the centuries, the followers of Christ have been persecuted because of their belief in him, and many of us can be proud that we have had among our ancestors men and women who died for the faith.
Today, too, there are still those who are suffering a lingering martyrdom, worse than quick death on the scaffold, because they obey God rather than man. We can help them to persevere, by our prayers. We ourselves, who are free from any overt persecution, must show our gratitude to God for being allowed to practice our religion openly and without fear, by doing just this. We must live according to the convictions of our Christian faith. We are here in this world for a few short years, our real and lasting home is in heaven. We must keep this thought uppermost in our minds, in all our doings and dealings.
As well as carrying out our own personal duties, we must remember the spiritual needs of our fellowmen. They, too, need to go to heaven and anything less will be eternal disaster for them. We may not be able to preach, or teach them the truth of the Christian faith, but we can and must help all those who are doing so.
Remember our Lord's words today. He who receives or gives hospitality and help to a prophet will have the reward of a prophet. He who helps those who are preaching and teaching the message of salvation, the good news of Christ, at home and abroad, will himself share in the reward of these preachers and teachers. When we get to heaven, one of the many pleasant surprises awaiting us will be the gratitude we will receive from saints we've helped to send to heaven, people we never knew or perhaps thought about. We helped those who thought about them and worked for their salvation, and we thus have a share in their reward.
Remember Christ's promise: even a cup of cold water will not go unrewarded, every little helping hand we give to bring our fellowmen to heaven will help us, too, toward the same goal. Heaven is our real goal in life—it alone will satisfy all our desires and it alone will last forever.
