Book excerpt: The world is a hydra-headed organism whose operations can take many forms and shapes based on how much you understand it and the moment you meet it. In my short stay on this terrestrial ball, I have observed that what you do not understand, you can hardly affect. And there is nothing more frustrating than attempting to change a thing you understand nothing about. For Daniel to influence Babylon, he had to understand the system; for Jesus to change the world He spent time in the temple listening to the teachers, asking them questions and learning from their answers. Understanding the world system is an important key to influencing it for God. Some Christians prefer to stay out of various sectors of human endeavour, preferring to simply pray and watch things happen. I think that Christians should get into all the aspects of human endeavour and bring Christ there. Whether it is in government or entertainment, in finance/economics or television, in fashion or sports, in literature or information technology, in academia or research, in manufacturing or caregiving, we should fully be there and represent the kingdom of God. Our absence has not made the world a better place; shying away, because we feel these sectors are dirty, is shying away from our duty to bring light into every part of the world. Where righteousness is absent, evil triumphs and holds sway. That evil continues to pollute the world and our children get contaminated and feel that the unrighteous way is the norm, and the righteous path the abnormal. But when we affirm the supremacy of Jesus in all these sectors, righteousness will subdue evil, and light will dispel darkness. If you are an ambitious Christian who intends to see Christ in every field of human endeavour, then this book will guide you using the example of Daniel, Hananiah, Mishael, and Azariah
