This was the title of my sermon on Sunday. The main question I tried to answer was: "Why doesn't the Bible clearly condemn the institution of slavery." I was helped the most with this question by Martin Lloyd-Jones, who addressed these matters in his sermons on Ephesians 6:5-9. He makes several very helpful points. Here is a sample quote:
"The primary business of the church is not to deal with conditions in this world, but rather with the Christian’s relationship to them, and with his conduct while he finds himself in them. As the Bible always puts its main and primary emphasis upon man in his relationship to God and his temporary relationship to this passing world, so must the church" (Life in the Spirit in Marriage, Home & Work: An Exposition of Ephesians 5:18 to 6:9, pg. 315).
Several factors need to be discussed in answering the above question, but certainly what Lloyd-Jones points out is most fundamental. The church must keep her priorities straight. The Gospel must be central in the mission of the church, and then as individuals are radically changed from the inside out, those individuals will most certainly have a profound impact on society. Lloyd-Jones goes on to say, "We are not to go out of the world, we do not cease to be citizens of this world; and we are to exercise certain functions as citizens while we are in this world. Yes, but we are to keep ourselves in the right place, in the right position. It is always a question of priorities, and of emphasis, of what comes first and of what comes second” (pg. 316).
