This link will take you to an audio recording of a sermon I delivered from the Gospel reading for Pentecost 18. It starts out a little bad and hard to hear, but it gets better after about 10 seconds. The sermon was delivered at my field education congregation, Beautiful Savior in Bridgeton, Missouri.
Mark 9:30-37 (English Standard Version)
Jesus Again Foretells Death, Resurrection
They went on from there and passed through Galilee. And he did not want anyone to know, for he was teaching his disciples, saying to them, "The Son of Man is going to be delivered into the hands of men, and they will kill him. And when he is killed, after three days he will rise." But they did not understand the saying, and were afraid to ask him.
Who Is the Greatest?
And they came to Capernaum. And when he was in the house he asked them, "What were you discussing on the way?" But they kept silent, for on the way they had argued with one another about who was the greatest. And he sat down and called the twelve. And he said to them, "If anyone would be first, he must be last of all and servant of all." And he took a child and put him in the midst of them, and taking him in his arms, he said to them, "Whoever receives one such child in my name receives me, and whoever receives me, receives not me but him who sent me."
