What does Paul pray for believers in the book of Ephesians?
Paul prays that believers might be filled with the wisdom of God and that they might know the height, depth, width, and length. Those are four dimensions, while we live in three, indicating a spiritual dimension in which believers already live.
Les explains that when he eventually gets to Ephesians, Paul makes a prayer for the believer that they might be filled with the wisdom of God and know the height, depth, width, and length. Les asks his classes how many dimensions that is: four, though we live in three. He says that shows there is another dimension we do not know physically, but spiritually we are already there and living in four dimensions.
