Then Joshua summoned all the tribes of Israel to Shechem, including their elders, leaders, judges, and officers. So they came and presented themselves to God. Joshua said to the people: “Fear the Lord and serve him wholeheartedly. Put away forever the idols your ancestors worshiped when they lived beyond the Euphrates River and in Egypt. Serve the Lord alone. But if you refuse to serve the Lord, then choose today whom you will serve. Would you prefer the gods your ancestors served beyond the Euphrates? Or will it be the gods of the Amorites in whose land you now live? But as for me and my family, we will serve the Lord.” The people replied, “We would never abandon the Lord and serve other gods. For the Lord our God is the one who rescued us and our ancestors from slavery in the land of Egypt. He performed mighty miracles before our very eyes. As we traveled through the wilderness among our enemies, he preserved us. So we, too, will serve the Lord, for he alone is our God.”

Joshua 24:1–2a, 14–17, 18b

Jesus was aware that his disciples were complaining, so he said to them: “Some of you do not believe me.” (For Jesus knew from the beginning which ones didn’t believe, and he knew who would betray him.) Then he said, “That is why I said that people can’t come to me unless the Father gives them to me.” At this point many of his disciples turned away and deserted him. Then Jesus turned to the Twelve and asked, “Are you also going to leave?” Simon Peter replied, “Lord, to whom would we go? You have the words that give eternal life. We believe, and we know you are the Christ, the holy one of God.”

John 6:61a, 64–69
