It’s A Battleground Out There

We preachers are always looking for good illustrations for our sermons. I went online recently and it took me hardly a second before I was confronted by a whole boatload of collections of sermon illustrations. They came with titles like The Preacher’s Sourcebook of Creative Sermon Illustrations, Hot Sermon Illustrations, Encyclopedia of Sermon Illustrations, The Ultimate Book of Illustrations and Quotes, 500 Sermon Illustrations for Busy Pastors, 1000 Illustrations for Preaching and Teaching… And if those weren’t enough, there was the blockbuster: 6000 Sermon Illustrations. At a sermon a week, you’d have enough illustrations to see you through more than a century!

Of course Jesus was the master of the illustration. Who doesn’t remember his parables of the farmer scattering his seed over the various types of soil, of the shepherd who searches high and low for his lost sheep until he finds it, or of the rich man and the beggar Lazarus at his gate?

In our passage from the sixth chapter of Ephesians this morning I can picture the apostle Paul pacing back and forth in his prison cell as he draws towards the conclusion of his letter to the young community of believers living in Ephesus. And I imagine him scratching his brain for an illustration to conclude all that he has been writing—something that would stick in the minds of his readers, something that they would carry away with them, perhaps for the rest of their lives.

In the previous five chapters he has covered a vast expanse of ground. The great nineteenth-century biblical teacher Handley Moule summed it up like this:

He has been telling them, from the beginning onward, of the secrets of eternal grace and love, of the wonder of their salvation from spiritual death, of their peace and life through faith, of their sealing by the Blessed Spirit, of their union with Christ their Head, of his blissful indwelling in their hearts, and then of the resultant life of humility, purity, love, truth, and every gracious duty of social holiness…

When you look back on it, he has given them a whole wagonload of vital truths to consider and challenges to act upon. Now Paul needs to draw all that he has been writing to a conclusion. What can he offer them that will help his readers to retain all this in their minds—and, more importantly, to put into practical action in their daily lives?

I can imagine Paul pacing back and forth in his cell. Then, deep in his thoughts, he pauses for a moment and glances around. And suddenly it comes to him. It was one of those head-slapper moments. Of course! How could he have missed it? The perfect illustration! There it was, staring right at him! It had been within feet of him all along: the Roman soldier standing guard at the door of his cell! As Paul’s eyes rest on the guard, it all becomes clear…

Paul lists six pieces of armour in all: the belt, the breastplate, the boots, the shield, the helmet and the sword. We don’t have time in the space of one sermon to examine them all, so this morning I want us to focus on just three of them: the breastplate, the helmet, and the sword.

The breastplate: protecting the heart

So first, the breastplate. This piece of armour covered the chest and shoulders, and was constructed out of a horizontal series of circular strips of iron fastened together with leather straps. The breastplate was designed to protect all the vital organs. But the most important one, and the one I want to focus on this morning, was the heart.

Were you aware that the word “heart” occurs more than eight hundred times in the Bible? And in almost every occurrence it is referring to something much deeper, and much more vital in many ways, than the physical organ that pumps blood through our bodies. For in the Bible the heart is the seat of the will. In biblical terms, it is the core of your inner being, the source of your emotions, your morals, your sentiments, your courage, your convictions and your resolve. The heart is what makes you “you”.

For this reason the Bible places enormous emphasis on what goes on inside our hearts. Here are just a few of the hundreds of examples you can find if you take the time to look for them:

• “You shall love the Lord your God with all your heart and with all your soul and with all your might.” (Deuteronomy 6:5)

• “The Lord does not look at the things people look at. People look at the outward appearance, but the Lord looks at the heart.” (1 Samuel 16:7)

• “With my whole heart I seek you…! I have stored up your word in my heart, that I might not sin against you.” (Psalm 119:10,11)
