Okay, so this week's assignment was the study of Paul's letters to the saints of Ephesus and Phillippi, as well as others to Timotheus (Timothy), Philemon, and the Hebrews. There had been a lot of things happening among the saints that are generally frowned upon in the Church, about which Paul wrote letters of instruction, exhortation, and encouragement to the Christians in those two cities.
For the Ephesians, Paul reminds them that salvation comes through the grace of the Savior (by way of our faith) after everything we have done for ourselves. The best part (I think) he teaches here is the Armor of God in chapter six. If we have a shield of faith, feet shod with the preparation of the gospel of peace, helmet of salvation, breastplate of righteousness, a girdle of truth, and a sword of the Spirit, we can stand against anything that Satan throws our way. Any missing piece of armor will give him the opening he needs to corrupt us and divert us from the path to eternal life.
Paul's lesson on the Armor of God to the saints of Ephesus is an excellent image of how we should best guard ourselves against temptation, and that the Adversary will do everything in his power to first remove our sword before anything else. Once the Spirit is gone, the rest of the armor will fall like a house of cards. So for all of us, Paul instruct us to remaint vigilant and stay on guard against the influences of Satan.
