Ephesians emphasizes the Gospel's twin pillars of change and choice. It explores how conversion (change) is a gift of God, which demands choices -- between disunity and unity, good and bad family life, good and bad social structures. The place that change and choice ever and again come together is in our liturgy and worship. Ephesians is filled with prayer and praise for our great and sovereign Lord, who shows us, as we worship him, that we cannot become a new creature without acting like one, and that knowing how to act can only come if we recognize the great change brought about in the new life in Jesus Christ. - Back cover.
