The lesson from the dungeon is that if you are going to be a servant of God, you are going to have to tell the truth--the good, the bad, and the ugly--no matter what. And you’re going to have to live with the blast furnace of criticism and opposition.
Witness the integrity of Joseph in this matter. Some people must have looked at him years later and said, "He became the prime minister of Egypt overnight."
No, he didn’t. God was fashioning Joseph for leadership in the crucible of suffering, hammering out his convictions on the anvil of life. And one thing God was teaching Joseph was this: "Joseph, tell the truth. Do what is right, because it is always right to do right." Joseph learned the lesson, and he stood out in the midst of malaise around him.
Just before his death, Paul told his spiritual son and disciple, Timothy, "Preach the Word … For the time will come when men will not put up sound doctrine. Instead, to suit their own desires, they will gather around them a great number of teachers to say what their itching ears want to hear" (2 Timothy 4:2-3, niv).
Calvin says, "All love to be flattered. Hence the majority of teachers, in desiring to yield to the corrupt wishes of the world, adulterate the Word of God."
