“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.” Ephesians 6:12 NLT
Christians are in a constant battle. From the moment a person puts their trust in Christ for salvation, the battle begins. Satan and his demons will do anything necessary to disrupt the lives of Christians in their new found faith. It has been said that once one becomes a Christian all their problems in this world go away, but the fact is they do not. For Christians living a godly life in a fallen world ruled by Satan is not only a big problem, but the fight of our lives.
The Lord does not leave us defenseless in our battle with the evil one. He promises to be with us through the Holy Spirit and He has provided us with a suit of armor to be able to stand firm in our struggles. The apostle Paul in writing to the church at Ephesus lists each part of the protective garb we are to put on. He instructs believers to, “put on every piece of God’s armor so you will be able to resist the enemy in the time of evil.” (Eph. 6:13a)
Christians are first instructed to put on the belt of truth, something that is lacking in our present day. Next is the body armor, or breastplate of God’s righteousness, signifying the Christian’s character. Our feet are to be fitted with shoes of the gospel of peace, the good news. To protect us from the fiery arrows of temptation, evil persuasions, and doubts, we are to take up the shield of faith. Faith in the God of our salvation will not permit any worldly darts to penetrate us. The helmet provides protection against serious head wounds. The helmet of salvation represents the believer’s assurance of salvation and is a symbol of military victory.
The five pieces of armor listed above are all for defensive purposes. It is of extreme importance that we note that Christians have only one offensive weapon, the Word of God. Only one is needed, and it is described as the sword of the spirit. It is indeed a weapon to use in the proper manner; used to instill truth, to bring to light what is false, to expose evil, to bring the good news of salvation, and to bring Glory to God. “For the word of God is alive and powerful. It is sharper than the sharpest two-edged sword, cutting between soul and spirit, between joint and marrow. It exposes our innermost thoughts and desires.” (Heb. 4:12)
‘The fight of our lives’ is true of every Christian life, but we can stand firm in truth, righteous character, peace, faith, assurance of salvation, and the Word of God.
