The 20th century gave rise to one of the greatest and most distressing paradoxes of human history: that the greatest intolerance and violence of that century were practiced by those who believed that religion caused intolerance and violence.
The idea that Christianity is basically a religion of moral improvement... has its roots in the liberal Protestantism of the late nineteenth century and early twentieth century... It is this stereotype which continues to have influence today... But then came the First World War... What had gone wrong was that the idea of sin had been abandoned by liberal Christianity as some kind of unnecessary hangover from an earlier and less enlightened period in Christian history.
A failure to understand something does not mean it is irrational. It may simply mean that it lies on the far side of our limited abilities to take things in and make complete sense of them.
The state is concerned with the promotion of outward righteousness arising from the individual being constrained to keep the law. The Gospel alters human nature, whereas the state merely restrains human greed and evil, having no positive power to alter human motivation.
Within each of us exists the image of God, however disfigured and corrupted by sin it may presently be. God is able to recover this image through grace as we are conformed to Christ. Just as the figure of David lay hidden within the marble, discernible only to the eye of its creator, so the image of God (however tarnished by sin) lies within us, see and known by God Himself. Yet God loves us while we are still sinners. He doesn't have to wait until we stop sinning. Acceptance of His love is a major step along the road that leads to our liberation from the tyranny of sin.
