Steve Lawson, The Unwavering Resolve of Jonathan Edwards:
[Jonathan] Edwards possessed a rare combination of Reformed theology, extraordinary giftedness, and fervent piety. However, it was this latter virtue — his true spirituality, marked by a fixed resolve — that positioned him to be used so mightily by God. Few have equaled his relentless pursuit of personal holiness. Edwards’ godliness fitted him to be the mighty instrument in the hand of God that he was.
