Classic Christianity contrasts the unchanging truths of God’s Word with the unstable philosophies of modern religion. Pastor W. M. Rench exposes the shallowness of “contemporary Christianity,” which molds itself to culture instead of Christ, and calls believers back to holiness, doctrine, and devotion. With biblical depth and pastoral conviction, he reminds readers that true Christianity is not driven by relevance or image but by the timeless truth of Jesus Christ, who is “the same yesterday, today, and forever.”
