Have you ever wondered what would happen if you put diesel in your vehicle instead of gas? First of all, don’t do it! Secondly, whether the car starts or not, it will eventually stop and no longer run. Your vehicle is made for one type of fuel. Putting in the wrong one will leave it powerless to drive.
So far in Ephesians we’ve been given an understanding of what God has done and is doing, and the great power He exercises to accomplish it. As we wrap up the first half of this book this last passage reminds us that for us to carry out the plan of God in our lives and in the Church we need God’s divine power to fulfill it. If we use any other power we will not be able to live as we have been called and commanded.
