The control Christians seek of the world is one always tempered by the law of God. The Fall of the House of Adam is a universal fact. Sin is disobedience to God, and a refusal to conform ourselves to His authority and revealed will. We all suffer from a moral genetic disease. We see disorder in our relationship to God, and in our estrangement from Nature.
Sin is the central problem of human existence.
The solution to the spiritual problem of sin is not government, but the gospel. Because we know from experience and revelation that men are sinners, Christians acknowledge the Conservative truth that no human being or society is perfectible. Schemes to create perfect social orders are therefore foolish and harmful. We note in Genesis that before the flood, humanity was already being effected genetically by the Fall. Giants were in the earth.
