In this article, Ed Welch argues that our deepest problem is sin. Welch maintains that dead sinners live, both judicially and dynamically, because Christ deals with the past, present, and future of sin. He studies 3 perspectives on sin prominent in Ephesians: Cravings, alienation and the concert of world, flesh and devil. Sin involves insatiable appetites, addictive false worship and separates people from each other and from God. Welch concludes that we are given Ephesians so that we who are still so prone to darkness and fog might learn to live as children of life.
