After almost 7 months of going through the book of Ephesians, we are finally coming to the conclusion of this powerful letter to the church in Ephesus. Now as we direct our attention to the apostle Paul's concluding remarks, we'll begin to see the complete picture, the very reason the apostle began to pen this letter in the first place. God calls us not merely to survive but to thrive. And thrive not just on our own irregardless of what happens to the world around us, but thrive as a people of God in order that we may be a witness to the world around us. For as we will see in our passage today, we are all engaged in an epic spiritual battle, of which the outcomes reverberate much further than any one of us could have ever imagined. So, let's dig deep and learn how we can be strong and stand firm in this fight.
