Reformed Theology: Sanctification

“Both Lutherans and Calvinists answered the question ‘What must I do to be saved?’ by saying that Spirit-worked repentance toward God and faith in the Lord Jesus Christ and His substitutionary work of atonement are necessary. But Lutherans had a tendency to remain focused on the doctrine of justification, whereas Calvinists, without minimizing justification, pressed more than Lutherans toward sanctification, which asks, ‘Having been justified by God’s grace, how shall I live to the glory of God?’” (Joel R. Beeke, Living for God’s Glory: An Introduction to Calvinism, p. 11).
