In today's Gospel reading from John 10, Jesus said to the Jews, "My sheep hear my voice; I know them, and they follow me. I give them eternal life, and they shall never perish. No one can take them out of my hand. My Father, who has given them to me, is greater than all, and no one can take them out of the Father's hand. The Father and I are one." Since the words of Jesus will not pass away, even when heaven and earth pass away (Matthew 23, Mark 13, Luke 21), these words were a great comfort to hear again at morning Mass.
