Grace in Pilgrim's Progress

“God's grace is the most incredible and insurmountable truth ever to be revealed to the human heart, which is why God has given us His Holy Spirit to superintend the process of more fully revealing the majesty of the work done on our behalf by our Savior. He teaches us to first cling to, and then enables us to adore with the faith He so graciously supplies, the mercy of God. This mercy has its cause and effect in the work of Jesus on the cross."

- John Bunyan: Pilgrim's Progress

Paradox of the Incarnation

"...there can be no getting around the essential paradoxicality of the Christian confession of Christ as Lord. 'Take away paradox from a thinker,' Soren Kierkegaard once quipped, 'and you have a professor.' Transposed into Christology, we may paraphrase the line as: 'Take away paradox from a theologian, and you have a heretic.'"
