"The kingdom of God is neither an unconditional divine gift sent down from heaven all at once, nor a simple human task to be completed in a few generations. It is both a gift and a task: an infinitely difficult, infinitely glorious divine-human undertaking requiring all God’s power and all man’s devotion, and even so stretching on from age to age as though it were endless."

"The difference between the law and the gospel does not at all consist in this: that the one requires perfect doing, the other only sincere doing – but in this: that the one requires doing, the other, not doing but believing for life and salvation. Their terms are different, not only in degree, but in their whole nature."
