K.P. Yohannan emphasizes that the only true solution to the pervasive issues of disease, hunger, injustice, and poverty in Asia is the Gospel of Jesus Christ. He illustrates the spiritual battle against Satan, who seeks to destroy lives, and highlights the futility of using physical means to combat such a powerful enemy. Through a personal encounter in Rajasthan, he recounts how the Gospel transformed a young man's life, showcasing the power of God's love and the urgency of sharing the message of salvation. The sermon calls for reliance on spiritual weapons to address the deep-rooted problems in society.

The only weapon that will ever effectively win the war against disease, hunger, injustice and poverty in Asia is the Gospel of Jesus Christ. To look into the sad eyes of a hungry child or see the wasted life of a drug addict is to see only the evidence of Satan’s hold on this world. All bad things, whether in Asia or America, are his handiwork. He is the ultimate enemy of mankind, and he will do everything within his considerable power to kill and destroy human beings. Fighting this powerful enemy with physical weapons is like fighting an armored tank with stones. I can never forget one of the more dramatic encounters we had with these demonic powers. It was a hot and unusually humid day in 1970. We were preaching in the northwestern state of Rajasthan—the “desert of kings.” As was our practice before a street meeting, my seven coworkers and I stood in a circle to sing and clap hands to the rhythm of Christian folk songs. A sizeable crowd gathered, and I began to speak in Hindi, the local language. Many heard the Gospel for the first time and eagerly took our Gospels and tracts to read. One young man came up to me and asked for a book to read. As I talked to him, I sensed in my spirit that he was hungry to know God. When we got ready to climb aboard our Gospel van, he asked to join us. As the van lurched forward, he cried and wailed. “I am a terrible sinner,” he shrieked. “How can I sit among you?” With that he started to jump from the moving van. We held on to him and forced him to the floor to prevent injury. That night he stayed at our base and the next morning joined us for the prayer meeting. While we were praising and interceding, we heard a sudden scream. The young man was lying on the ground, tongue lolling out of his mouth, his eyes rolled back.
