It is often and truly said that the gospel message…turns people’s live upside down. Less frequently it is noted that the anti-God syndrome in our system, called original sin, had turned out lives upside down already, so that this inverting change of heart by the Spirit, commonly called conversion, actually sets us right way up, to live in the way truly natural to us for the first time ever.

– J.I. Packer in Evangelicals and the Way of Salvation
