So what is a Christian to do? Can Christians shun all political and social efforts to affect the culture? Certainly, if our consciences convict us to do so and as long as our motivation is pure and not an effort to appear holier than those who do choose to be involved.
Pride is too often the by-product of completely withdrawing from the culture. We are to be in the world, but not of it, and part of being in the world is modeling Christ-likeness for the world and Christian love toward one another.
