The design of God in our cancer is not to train us in the rationalistic, human calculation of odds. The world gets comfort from their odds. Not Christians. Some count their chariots (percentages of survival) and some count their horses (side effects of treatment), but we trust in the name of the Lord our God (Psalm 20:7). God’s design is clear from 2 Corinthians 1:9: “We felt that we had received the sentence of death. But that was to make us rely not on ourselves but on God who raises the dead.” The aim of God in our cancer (among a thousand other good things) is to knock props out from under our hearts so that we rely utterly on him. - John Piper, Don't Waste Your Cancer, Crossway Books.
