"I appeal to you to seek the Lord with me concerning the place of fasting and prayer in breaking through the darkened mind that engulfs the modern world, in regard to abortion and a hundred other ills. This is not a call for a collective tantrum that screams at the bad people, “Give me back my country.” It is a call to aliens and exiles in the earth, whose citizenship is in heaven and who await the appearance of their King, to “do business” until he comes (Luke 19:13). And the great business of the Christian is to “do all to the glory of God” (1 Cor. 10:31), and to pray that God’s name be hallowed and his kingdom come and his will be done in the earth (Matthew 6:9-10). And to yearn and work and pray and fast not only for the final revelation of the Son of Man, but in the meantime, for the demonstration of his Spirit and power in the reaching of every people, and the rescuing of the perishing, and the purifying of the church, and the putting right of as many wrongs as God will grant."
