R. C. Sproul Jr. has equipped Christians with the ammunition needed to counter the non-Christian philosophies that have made the greatest gains in our era. He also counters the primary criticisms lobbed against the biblical world-view. “My hope is to persuade others and to provide some tools to help others persuade others,” writes Sproul, “My goal is to not only tear down the strongholds of the devil, and not only repel the assaults of the very gates of hell, but to show that the foundation upon which our faith stands is firm."
