It has been a few weeks since we were in Ephesians. The last sermon I preached was on the shoes of the gospel of peace. I have a confession to make, and it is not one to be proud of: I am not very good at creating space for my own rest. One of the symptoms that a break and vacation is needed is when your pastor takes 15-20 minutes to talk about shoes during his sermon introduction! In preparation for this sermon, I have been thinking about the importance of rest as it is related to faith.
One of the Ten Commandments is to, “Remember the Sabbath day, to keep it holy” (Exod. 20:8-11). Here is the irony with the fourth commandment: The first four commandments address our relationship with God and the last six commandments address our relationships with one another. I am of the opinion that a Sabbath rest has less to do with the seventh day of the week and more to do with our need to separate ourselves from the noise of life. Regarding the fourth commandment, Jesus said: “The Sabbath was made for man, and not man for the Sabbath” (Mark 2:23-28). The purpose of the Sabbath is that it creates space for you to listen to God for the purpose being strengthened in Him.
The reason why the fourth commandment is sandwiched between the first three concerning our vertical relationship with God and the final six concerning our horizontal relationships with your neighbor is because if you ignore a Sabbath rest, both your relationship with God and your relationships with others will suffer. If you ignore the fourth commandment, you will be more prone to develop idols in your heart and become little good to those around you. So, here is what I want you to hear as we move forward: Sabbath rest stabilizes gospel grounded faith. The kind of rest I am talking about must include the kind of rest described in Psalm 46:10, “Stop striving and know that I am God; I will be exalted among the nations, I will be exalted on the earth.”
Now, with God’s command for a Sabbath rest as our backdrop, let’s consider again the armor of God:
“Finally, be strong in the Lord and in the strength of His might. Put on the full armor of God, so that you will be able to stand firm against the schemes of the devil. For our struggle is not against flesh and blood, but against the rulers, against the powers, against the world forces of this darkness, against the spiritual forces of wickedness in the heavenly places. Therefore, take up the full armor of God, so that you will be able to resist on the evil day, and having done everything, to stand firm.” (Eph. 6:10–13)
Remember that the schemes belong to the devil, but the armor we are to put on belongs to God. The belt of truth is our identity in Christ, the breastplate of righteousness is our righteousness in Christ, and the shoes of the gospel of peace enable us to keep our footing in the whole Gospel, that includes our salvation but also the full redemption of all creation. The whole Gospel includes our resurrection, but it also promises us a day when sorrow and sighing will flee away: “And the redeemed of the Lord will return and come to Zion with joyful shouting, and everlasting joy will be on their heads. They will obtain gladness and joy, and sorrow and sighing will flee away” (Isa. 51:11).
The fourth piece of God’s armor is the shield of faith. The questions we need to answer are what is it really; and how does one use the shield of faith?
What is the Shield of Faith?
The shield Paul had in mind was not the small round shield you would expect a soldier to have for hand-to-hand combat, for it was light but left most of the body exposed. Instead, the shield Paul envisioned was more like the one a soldier carried to protect his whole body from the enemy’s arrows shot from a distance.
The large shield was called a “scutum” and was typically used by Roman legionaries. It was designed not only to protect the soldier wielding it from arrows, but was designed especially to protect him from arrows that were dipped in pitch and lit on fire before they were launched. The front of the shield was covered in leather that could be soaked in water; in this way, when the flaming arrows hit the shield, the fire would be quenched.
For what purpose did a flaming arrow (aka “fire arrow”) serve? What is fire known for doing? The enemy would launch flaming arrows to set on fire anything that was flammable such as buildings, materials, and enemy troops. Fire consumes and destroys, and this is exactly what the rulers, powers, world forces of this darkness, and the spiritual forces of wickedness in the heavenly places desire to do to any and all of God’s people. We are told to take up the shield of faith to protect us from such attacks from the enemy, but what is it?
Is the shield of faith a self-determined will to hold on to what you believe? Is it something that you would have more of if you simply believed more? Is the shield of faith more about having enough faith in what we read about in the Bible so that you can claim financial, emotional, relational, spiritual, and physical healing and wholeness for yourself? I don’t think the shield of faith includes any of that.
Remember that Paul did not just come up with the armor of God because of some Roman soldiers around him. Paul received his shield metaphor from the Old Testament. To address Abraham’s fear about being without an heir, God promised Him, “Do not fear Abram, I am a shield to you; your reward shall be very great.” In Psalm 28:7, David celebrated the God who hears the prayers of His people with these words: “Blessed be the Lord, because He has heard the sound of my pleading. The Lord is my strength and my shield; my heart trusts in Him, and I am helped; therefore my heart triumphs, and with my song I shall thank Him.” However, I think Proverbs 30:5 is the most helpful verse that helps us understand what the shield of faith is: “Every word of God is pure; He is a shield to those who take refuge in Him.”
So, which is it? Is God our shield and if so, how can our faith be the shield? On this point Iain Duguid is helpful: “Faith is the means by which we flee to God for refuge. It is how we cling to God and find in him comfort and protection in times of difficulty and distress.”[1] It is one thing to believe that God exists but is quite another thing to flee to the God you know to be true because of the way He has revealed Himself through His Word. The more you know about God, the more inclined you will be to flee to Him as your refuge and strength, for the Bible says, “the people who know their God will be strong and take action” (Dan. 11:32b).
The way you cling to God and find Him to be your comfort and protection is through His Word! We are told in Ephesians 5:26 that Jesus intends to sanctify and beautify His church through the washing of water with the word. It is the word of God that we use to saturate our shield “to extinguish all the flaming arrows of the evil one.” This is not a New Testament concept; it is a Genesis through Revelation principle for living faithfully before God. Listen to Psalm 119:10-11 and tell me if you cannot hear the same tone that you hear in Ephesians 6:16, “With all my heart I have sought You; Do not let me wander from Your commandments. I have treasured Your word in my heart, so that I may not sin against You.”
How do We Use the Shield of Faith?
It is all well and good to know what the shield of faith is, but how do you use it? To answer that question, permit me to show you something that I have read dozens of times and missed because I did not read Ephesians 6:14-17 as carefully as I should have. There are six pieces that belong to the armor of God. The first three are all pieces that a soldier puts on and keeps on so long as he is active:
- “...having belted your waist with truth” (v. 14a)
- “...having put on the breastplate of righteousness” (v. 14b)
- “...having strapped on your feet the preparation of the gospel of peace” (v. 15)
Each of these pieces are attached to the Christian as part of his/her identity in Christ. The belt of truth is your new identity in Christ, the breastplate of righteousness is your righteousness in Christ, and the shoes of the gospel of peace are the promise of full redemption that Jesus makes possible. You put on these pieces of armor by standing in the gospel, confidently recognizing that all your righteousness is in Christ, and that your identity is rooted in Christ as truth for all of life!
Now notice the final three pieces of the armor of God and how Paul distinguishes them from the first three pieces with the words, “in addition to all...”:
- “...taking up the shield of faith” (v. 16)
- “...take the helmet of salvation” (v. 17a)
- “...take the sword of the Spirit, which is the word of God” (v. 17b)
The soldier’s shield, helmet, and sword were all a part of his armor, but they were pieces he could take up and put down at will. The enemy can tempt you to believe that Christ is not enough, but what he already knows is that your righteousness is Christ’s righteousness; wearing the breastplate of righteousness is simply walking in light of that truth. However, when the enemy attacks with his flaming arrows in the form of temptations, lies, and accusations, you can choose to take up the shield of faith or allow those arrows to pierce you so that their fire can overwhelm, consume, and incapacitate you.
If you are a Christian and you have truly been born again, the flaming arrows may not be able to destroy your soul, but they certainly can wound to the point of rendering you immobile and unable to fully engage and participate in God’s mission in the world and purpose for your life. If you are a Christian, the enemy knows that God chose you before the foundation of the world (Eph. 1:4-6), that you were fully and completely redeemed by the blood of His Son (1:7-12), and that you have been sealed by the Holy Spirit as God’s inheritance to receive all of His promises (1:13-14, 18-23).
In fact, I am convinced that the devil has more of a theological grasp over what it means for you to be a Christian than many Christians, but if he can deceive you, if he can aid in destroying your Christian witness, if he can paralyze you with shame and guilt to keep you from clinging to all that the cross of Christ represents, then he will do all within his ability to do just that! Dear Christian, when those flaming arrows come, you have a shield God has given that you can take up to defend yourself from such attacks! God has given us all that we need, but faith in His promises, a dependance upon Him, and the responsibility to proactively saturate our faith with the word of God is something we must do.
Conclusion
The enemy will launch his flaming arrows but make no mistake from what we have learned so far from Ephesians, there is also the danger we face from self-inflicted wounds when we fall into temptation. The devil never makes us sin, we do that all on our own! This is why it is important to take on the full armor of God. When we are mindful that Jesus is our identity and not our sin, when we are fully aware that Jesus is our only hope and righteousness, and then stand in the truth of all of God’s redemptive promises, our resolve to resist sin and temptation becomes more determined.
But, when the flaming arrows fly you can lower your shield and let them pierce and consume, or you can take up your shield. When the enemy whispers: “You sinned and now you are too disgusting for God to love you!” You take up your shield saturated with the word of God and say: “Do not rejoice over me, enemy of mine. Though I fall I will rise; though I live in darkness, the Lord is a light for me... He will bring me out to the light, and I will look at His righteousness” (Micah 7:8, 9). You take up your shield saturated by the word of God and say, “God demonstrates His own love toward us, in that while we were still sinners, Christ died for us.... For if while we were enemies we were reconciled, we shall be saved by His life” (Rom. 5:8, 10).
Don’t you think that Mary and Joseph endured many the constant barrage of the enemy’s flaming arrows the moment they found out about the conception of Jesus while Mary was still a virgin? Gabriel appeared to Mary and told her: “Do not be afraid, Mary, for you have found favor with God. And behold, you will conceive in your womb and give birth to a son, and you shall name Him Jesus” (Luke 1:30-31). Her only question was: “How?” since she was a virgin. After the angel told her that the Holy Spirit would make it possible miraculously, her response was simply: “Behold, the Lord’s bond-servant; may it be done to me according to your word” (v. 38). Mary could have been overwhelmed by fear over what her mother, father, relatives, and neighbors would think, but instead she raised up her shield of faith in the form of a song saturated with what she knew from the word of God:
“My soul exalts the Lord,
And my spirit has rejoiced in God my Savior.
“For He has had regard for the humble state of His bond-servant;
For behold, from now on all generations will call me blessed.
“For the Mighty One has done great things for me;
And holy is His name.
“And His mercy is to generation after generation
Toward those who fear Him.
“He has done mighty deeds with His arm;
He has scattered those who were proud in the thoughts of their hearts.
“He has brought down rulers from their thrones,
And has exalted those who were humble.
“He has filled the hungry with good things,
And sent the rich away empty-handed.
“He has given help to His servant Israel,
In remembrance of His mercy,
Just as He spoke to our fathers,
To Abraham and his descendants forever. (Luke 1:47–55)
Joseph could have walked out on Mary in disbelief, but He took up his shield as well and believed that God was not only big enough to make the conception of Jesus supernaturally possible, but he too believed the word of God: “Behold, the virgin will conceive and give birth to a Son, and they shall name Him Immanuel” (Isa. 7:14; see also Matt. 1:18-25).
So, how do you use the shield of faith? How do you take it up to defend yourself? You take up the shield of faith each time you flee to God for refuge through the truth of His word and cling to Him to find your comfort and protection in times of difficulty and distress.
