For this week in Lent, the Prayerbook focuses on spiritual warfare, the battle against the demonic but also against sin and those under its power. The Epistle reading, from Ephesians 5, restates certain sins from last week but adds our need to reprove them by living in the light of Christ. The Gospel reading is from Luke 11, where Jesus casts out demons and then warns about both the dangers of a house divided and a house left vacant. You are either actively with Jesus or you are against Him. The Old Testament lessons begin the saga of Joseph, from Genesis 39 and 42.
