I am surely committed to the need of consistency. I must be consistent first and foremost in my own positive presentation of God’s truth, and secondly, by demonstrating the inconsistencies of those who oppose that truth, I seek their salvation as well as that of those who would be misled by them. And the reason I am fully committed to the defense of, and the centrality of, the gospel of grace finds its origin and source in the very same commitment to consistency that drives my apologetics. –James White
