Published by Ligonier Ministries in 2020, after Sproul's death, as part of the Crucial Questions series; Ligonier describes it as drawn from his teaching. It argues that Christian faith is rational because it rests on the promises of God, who has proven trustworthy in his Word. Ligonier has given away the ebook editions of the series free since 2013.
