For those looking for a guided Bible study or genuine "life lessons," look elsewhere, since there isn't much here. It attempts to be heavy in application, but even that mission is distorted by poor context, some odd questions, strange idioms and cliched writing, and a weird 2nd person "Inspiration" bit in every chapter that accuses the reader of things like, "And you thought God adopted you because you were good looking" and other things the majority of Christians have never thought of.
Each chapter is broken down into several sections, several with empty space so that the reader can write in the book itself:
Reflection: While it might seem odd to start each chapter with a reflection rather than end it, these short intros set a mood/mindset of something to think about before diving into the study. Things like, "Think of a Time when you felt a true sense of belonging," and "how would you explain what it's like to be merciful to someone?" etc.
Situation: The next section is a short paragraph in each chapter giving *very basic* context to the piece. Unfortunately, this big picture view often skips over essential context relevant to the passage. For example, the "Situation" section for chapter one basically says Paul sent a letter to a bunch of churches and that he'd spent a few years with the Ephesian church, and that the purpose of the letter was to give encouragement and an overview of the Christian life. Not wrong, per se, just pretty vague. Leaving out that the Ephesian church was a mostly Gentile church, which is highly relevant to Paul's assurance that they to are included in Christ and that it was the plan of God all along, seems like some pretty crucial missing context.
Observation: This section is the chapter's passage presented in two different translations, the NCV and the NKJV. I like the use of two different translations here - they both are good translations, the NCV more an accessible thought for thought and the NKJV leaning closer to a decent word for word.
There aren't any tips on observation or aids for Bible Study, though, so this is good for those who dislike commentary in their scripture, but might be difficult for those unused to self-studying a passage.
Exploration: This is a series of application questions, some more clearly tied to the passage just read than others. Things like, "What specific changes have occurred because of Christ's presence in your life?" and "What part of the body [of Christ] are you?" This is probably the strongest section of the book as the questions are good for reflection.
Inspiration: This section is Max Lucado talking to the reader in 2nd person (you think, you know...) In this section he usually sets up a false belief, sometimes a very silly false belief (like the aforementioned 'you thought God saved you because you were good looking,') or a belief very few Christians would hold (like believing grace and mercy are somehow exclusive,) and providing the answer amid a flurry of cliches. For the most part there is little depth here, and all these sections are taken from his other books (God Came Near, The Great House of God, The Gift of Blessing, etc.)
Reaction: This is a list of questions, very similar to the Exploration section, though a few seem pretty abstract or slightly misleading. (For example, "What can you draw from the statement that God chose us from the Foundation of the World?" noteably leaves out the crucial phrase "in Christ" found in the actual verse. This could potentially cause a reader to over-individualize the verse or fail to note that God chose those "in Christ" before the foundation of the world, not God choosing individuals to become in Christ.) For the most part this is another decent section - pretty much most of the value of the book is in the questions.
Life Lessons: This is a short paragraph with basic lessons like "Everything rests on Jesus Christ" and "Without God's mercy and grace, we're stuck in imperfect." Few insights even casual readers of the Bible wouldn't come up with.
Devotion: This section is a little prayer, followed by further verses to read, and a redundant reference to the passage just read.
Journaling: The concluding section gives one question or task the reader can think on and write about. These are very application focused. Oddly, the last chapter doesn't have this journaling page and uses the spot for advertising the other "Life Lessons" books.
If you's really love somewhere to start when it comes to application, then this might be a decent read just for the questions. Otherwise, there isn't a lot of content/insight/context on the book of Ephesians itself in this.
