" The primary problem concerning Christianity’s role in changing the modern world is that most Christians no longer believe we are capable of accomplishing that change. This is a direct result of the fact that Christians by and large don’t believe that holiness is possible. But it is also deeply connected to a false belief widely held by Christians that the culture has become so powerful that we are simply incapable of transforming it. This leads to conversations that the culture has pushed the envelope too far and the only solution is the Second Coming of Jesus Christ. This is tragic defeatism, which is the antithesis of the spirit of Christianity and at the same time an astounding form of spiritual laziness. It is nothing more than the fruit of the biggest lie in the history of Christianity. It is only because we have been deceived into believing holiness is not possible that we would believe the culture is too negative and too strong to be transformed by Christianity. The world needs to be transformed, and nobody is in a better position to do that than Christians. In fact, I would argue that if Christians do not change the world, it will not change for the better.
