Ephesians is perhaps the most spiritual letter that Paul wrote, and that indicates that the church in Ephesus at that time was in a very spiritual state. It was a very good church. There was nothing there for Paul to correct. Ephesians deals with living a heavenly life on earth. A church and a Christian can fulfil their function on earth only if they are heavenly-minded. The more heavenly-minded you are, the more you can fulfil God’s purpose for you on earth. The more earthly-minded you are, the more useless you will be to fulfil God’s purposes on earth, even if you say you are going to heaven when you die. Your home can fulfil its function for God only if it is a heavenly-minded home. The Lord’s will for us is “that your days on earth may be like the days of heaven upon earth” (Deuteronomy 11:21 – KJV). This was not possible under the old covenant. But Ephesians tells us how we can live like that under the new covenant.
