A Commentary on Ephesians by David Pawson and published by Anchor Recordings Limited.
Unlike Paul's other letters, this one is not addressed to particular churches or individuals, with their own needs and problems (even "Ephesians" is not in all the early copies). It is a circular despatch, covering general matters of belief (chapters 1-3) and behaviour (chapters 4-6), applicable to all churches and Christians everywhere. It is one of the clearest statements in the New Testament of God's purpose in saving us and is as practically challenging as it is spiritually inspiring. Perhaps that is why it is such a popular choice for preachers.
