Our world is full of challenges to improve our moral behavior. But how does the Gospel of Jesus call the Church to holiness? Alistair Begg shows how the Christian’s holiness is achieved not by man’s moral behavior, but by the atoning work of Christ. Unlike the sacrificial animals of the Old Testament, Jesus volunteered for His sacrifice, bearing God’s wrath. Now that He has secured victory over sin and Satan, we can confidently join His good work, knowing that He will complete God’s mission in us.
