Therefore put on the full armor of God, so that when the day of evil comes, you may be able to stand your ground, and after you have done everything, to stand. Stand firm then, with the belt of truth buckled around your waist, with the breastplate of righteousness in place, and with your feet fitted with the readiness that comes from the gospel of peace. In addition to all this, take up the shield of faith, with which you can extinguish all the flaming arrows of the evil one. Take the helmet of salvation and the sword of the Spirit, which is the word of God. And pray in the Spirit on all occasions with all kinds of prayers and requests. With this in mind, be alert and always keep on praying for all the saints. (Eph.6:13-18)
In his discussion of wrestling against spiritual powers, Paul, in addition to other weapons and armor, tells us to take up the shield of faith. The Roman army used various shields but, according to Strong, the word Paul used here denotes the large rectangular shield that covered the entire body. They were made in such a way that they could be hooked together with the shields of other soldiers to form an almost impenetrable wall in combat.
In so many words, Paul suggests that faith is the ultimate defense against any assault of the enemy. Faith is believing God. It is not just believing in God or that God exists, but it is believing that whatever God has said or promised is true and can be absolutely trusted. Satan deals in doubt and half-truths designed to undermine our faith and trust in God. He has operated that way from the beginning. In the Garden, Satan raised questions about God’s integrity and his commitment to Adam and Eve’s good. Satan twisted the words of God, suggested that God was withholding wisdom out of his own desire to keep Adam and Eve from being all that they could be, and simply declared that God was a liar when he told Adam and Eve that they would not actually die if they ate from the Tree of the Knowledge of Good and Evil as God had said. His words created doubt in the hearts of the first man and women about whether God and his word could be trusted. Once doubt cast its shadow, they abandoned the directives of God and went their own way resulting in the loss of their place in paradise.
Satan still deals in smoke and mirrors, threats, lies, and accusation. Faith in God quenches the flaming arrows of the enemy. Ultimately the answer to every temptation is to stand invariably on the Word of God. Of course, that requires knowing the Word. It also requires a firm conviction that God is good and that God is love. That conviction is what makes us willing to do all things God’s way because we believe that “His way” is always in our best interest because he always loves us.
Jesus modeled this principal throughout the gospels. When confronted with temptation in the wilderness, Jesus declared the word of God in response to Satan’s offers. After three attempts to draw Jesus into agreement with him, Satan abandoned his attack and left. James tells us to “Resist the devil and he will flee from you” (Ja.4:7). But how do you resist the devil? The verse immediately prior to the one just quoted tells us to “Submit, therefore, to God.” In the original language the word translated “submit” means to surrender, to yield, or to line up under your commander as a soldier standing in formation.
We submit to God by aligning ourselves with Him and his word and surrendering our thoughts, our words, and our ways to his. When we do that, the devil flees because he cannot exercise any power or authority over those whose faith is truly in God. That faith shields us from every attack and extinguishes his attempts to draw us away from the God who is our protector. To those who love and serve Him, God says, “If anyone does attack you it will not be my doing. Whoever attacks you will surrender to you…no weapon forged against you will prevail and you will refute every tongue that accuses you” (Isa.54:15-17). That promise applies not only to your enemies in the natural realm but also in the spiritual realm as well. Therefore, take up the shield of faith and ask the Father for even greater faith on a daily basis. When the enemy comes against you today, be strong in the Lord, stand on his Word, and wield the shield of faith.
