10 A final word: Be strong in the Lord and in his mighty power. 11 Put on all of God’s armor so that you will be able to stand firm against all strategies of the devil. 12 For we are not fighting against flesh-and-blood enemies, but against evil rulers and authorities of the unseen world, against mighty powers in this dark world, and against evil spirits in the heavenly places. 13 Therefore, put on every piece of God’s armor so you will be able to resist the enemy in the time of evil. Then after the battle you will still be standing firm. 14 Stand your ground, putting on the belt of truth and the body armor of God’s righteousness. 15 For shoes, put on the peace that comes from the Good News so that you will be fully prepared. 16 In addition to all of these, hold up the shield of faith to stop the fiery arrows of the devil. 17 Put on salvation as your helmet, and take the sword of the Spirit, which is the word of God. 18 Pray in the Spirit at all times and on every occasion. Stay alert and be persistent in your prayers for all believers everywhere. 19 And pray for me, too. Ask God to give me the right words so I can boldly explain God’s mysterious plan that the Good News is for Jews and Gentiles alike. 20 I am in chains now, still preaching this message as God’s ambassador. So pray that I will keep on speaking boldly for him, as I should.
The reality of the Christian life is that we are destined to face opposition from the spiritual forces around us. The facts are that we have an enemy whose sole aim is to thwart God’s plan and frustrate our efforts in serving Him at every turn. Here in Ephesians Paul doesn’t try to minimize or dilute the struggle as he warns us of a very real war, saying “our struggle is not against enemies of blood and flesh, but against the rulers, against the authorities, against the cosmic powers of this present darkness, against the spiritual forces of evil in the heavenly places.” So what do these spiritual forces want to do? They want to stand in opposition to God. What God wants to build up they will do their best to break down. God through the death of His Son Jesus Christ has broken down the dividing wall of hostility between people, regardless of gender, race, or culture. So the devil and his demons will try to rebuild that barricade whether racial, socioeconomic or gender based. God’s goal is for his people to live together in harmony and purity. So the powers of evil will try to sow seeds of discord and sin so they can create conflict in the church. We should never underestimate the danger that the devil possess. As Christian’s we can’t afford to become comfortable and complacent when it comes to the conflict. We should never take for granted our victory over sin. We should never stop being on guard and fighting temptation. Which also means that we should not be surprised and shocked when we see Christian leaders give into sin as they fall into the trap of temptation. Until Christ returns to take us to our home in heaven we will have to face and fight many spiritual battles. In the midst of the fight we need to keep a proper perspective, we need to focus on the peace that is ours, which was bought by the blood of Jesus. This is both a purchased peace as well as a promised peace. It’s a peace that provides a steady platform in the midst of this relentless struggle against evil. While the war has been won the battles continue. We should never underestimate or discount the devil. Paul describes the devil and his followers as powerful, evil and cunning. They’re the rulers and authorities, the cosmic powers of this present darkness. Until Christ returns they will continue to wield their power. Christ has won the victory but they continue to fight, with ever increasing intensity and desperation as their end approaches. We need to also be careful not to mistake their intentions which are always evil, Paul calls them, spiritual forces of evil in the heavenly places. We find ourselves in a battle against spiritual forces whose sole desire is to lure us into sin so they can conquer and rule over us as they lead us away from following Christ. Paul also reminds us here that the devil is a wily opponent. That is, he combines tactical shrewdness with ingenious deception. Jesus called the devil the “Father of lies” John 8:44. His workers are described as wolf’s in sheep’s clothing, Matthew 7:15. 2 Corinthians 11:14 tells us that He even disguises himself as an angel of light. One of Satan’s great strategies is stealth, to convince people that he doesn’t exist. People rarely talk about the devil any more, except maybe as a joke when they say “Oh, the devil made me do it!” But do you see that is one of Satan’s’ greatest successes. If you don’t believe in the devil, you won’t be worried about his lies and temptations. When we believe the lie that he is just a children’s fable we ignore him because in our arrogant wisdom we have outgrown that sort of childishness. So we fall victim to his schemes because we never see him coming. But don’t be fooled, the devil is very real. He is an opponent working in opposition to everything God is for and he should be seen as an enemy to be reckoned with. What we’re fighting against isn’t just human weakness. Psychological counselling and self-help groups will solve some problems, but they won’t help with this battle. So how do we experience success on the spiritual battlefield? By standing in in the Lord’s strength not ours. You see basic to the effective Christian life is preparation. For it is the unprepared believer who becomes the defeated believer, the one who tries to stand in their own strength and wisdom. The strength of the Christian life is dependence on God, being strong. We are to be strong in the Lord, and in the strength of His might. Any other strength proves to be impotent. To ‘be strong’ here means to be made strong, to be strengthened because alone we are weak. Notice here that Paul does not say to be strong by the Lord, but ‘in the Lord.’ When life is lived in union with him, walking in his will, where we are connected to him as branches are to the vine, then there need not be failure due to powerlessness. As 1 John 2:14 states, “I have written to you who are God’s children because you know the Father. I have written to you who are mature in the faith because you know Christ, who existed from the beginning. I have written to you who are young in the faith because you are strong. God’s word lives in your hearts, and you have won your battle with the evil one.” The reason for spiritual success in the battle revolves around living in relationship with the Lord. Apart from Him the Christian can do nothing, as John 15:1–5 clearly states, but in Him we have available all the strength of His might. The cardinal reality presented in the book of Ephesians is that, as believers, we are in Christ and are one with Him. His life is our life, His power our power, His truth our truth, His way our way, and, as Paul goes on to say here, His strength is our strength. Only the Lord’s strength is sufficient for the battle. So let me ask you whose strength are you standing in the Saviors or self?
