20, 21. What do Jehovah’s Witnesses incessantly proclaim, but what do the leaders of Christendom refuse to do?

²⁰ The prophecy says of such ones: “Those to whom he has said: ‘This is the resting-place. Give rest to the weary one. And this is the place of ease,’ but who were not willing to hear.

Isaiah 28:12, 13.

²¹ Incessantly, just as Isaiah spoke God’s message, Jehovah’s Witnesses tell Christendom that she should rest her hope in Jehovah’s word. But she refuses to listen. To her, the Witnesses seem to be babbling in a foreign tongue. They speak a language she cannot understand. Christendom refuses to give rest to the weary one by telling about God’s Kingdom and the new world to come. Rather, she is drunk with the wine of her relationship with this world. She prefers to support political solutions to mankind’s problems. Like the Jews of Jesus’ day, she has not sought the Kingdom resting-place herself, and she will not tell others about it.​—Matthew 23:13.
