Why are some teachings in Ephesians not found in Romans, Galatians, or Corinthians?
Ephesians presents a deeper level or higher ground of Christian experience. The Apostle Paul brings out truths in Ephesians that he does not bring out in Romans, Galatians, or Corinthians. This is because Ephesians is described as higher ground and deeper water, addressing a deeper level of Christian experience.
Les teaches that Ephesians is again a deeper level of Christian experience, or a higher, however you want to look at it. He explains that Paul will bring things out in Ephesians that he doesn't even bring out in Romans and Galatians and the Corinthians, because this is higher ground and deeper water. In the surrounding context, Les connects this to being in Christ, explaining that salvation is an act of God that places believers in Christ and resurrects them from darkness into life. He emphasizes that God Himself declares there is now therefore no condemnation for those who are in Christ.
