The theme of Chapter 5 in the the Made to Crave Bible Study hosted by Proverbs 31 Ministries. is in the third paragraph:
Succumbing to temptation "does matter and not just for the physical or mental setback. It's the denial of a fundamental spiritual truth that will make a healthy eating plan fall apart time and time again. What is this truth? We were made for more than this. More than this failure, more than this cycle, more than being ruled by taste buds. We were made for victory. Sometimes we just have to find our way to that truth."
She goes on to say that we need to rewrite the "scripts" that play in our heads, the wrong thought processes and reactions, and replace them with new ones. The first one is this truth that God's power is available to us:
16 I do not cease to give thanks for you, remembering you in my prayers, 17 that the God of our Lord Jesus Christ, the Father of glory, may give you the Spirit of wisdom and of revelation in the knowledge of him, 18 having the eyes of your hearts enlightened, that you may know what is the hope to which he has called you, what are the riches of his glorious inheritance in the saints, 19 and what is the immeasurable greatness of his power toward us who believe, according to the working of his great might 20 that he worked in Christ when he raised him from the dead and seated him at his right hand in the heavenly places.
Lysa then discusses this passage phrase by phrase. Some versions say, "I keep asking...," reminding us that we can continually bring these things before the Lord. That we're praying to out father reminds us of our identity as His children, and Lysa brings out a great deal about focusing on out new identity in Him. The passage also reminds us of the deeper reasons for whatever we're going through, that we might come to know God better. And then we can look to "the hope of His calling" and His power, the very power that raised Christ from the dead.
