God: "I looked for someone to take a stand for me, and stand in the gap" (Ezekiel 22:30)
A God-centered theology must be a missionary theology. If you say that you love the glory of God, the test of your authenticity is whether you love the spread of that glory among all the peoples of the world. Or another way to say it is that worship is the fuel and the goal of missions. Missions exists because worship doesn't. God's passion is to be known and honored and worshipped among all the peoples. To worship him is to share that passion for his supremacy among the nations.
Social ethics must never be substituted for personal ethics. Crusading can easily become a dodge for facing up to one's lack of personal morality. By the same token, even if I am a model of personal righteousness, that does not excuse my participation in social evil. The man who is faithful to his wife while he exercises bigotry toward his neighbor is no better than the adulterer who crusades for social justice. What God requires is justice both personal and social.
