We live on a battlefield, and it isn't even our home turf we are fighting for. Our home is in heaven, we are strangers and aliens here. Satan wants to subdue us, break us, entice us into a snare and immobilize us. We are warned to remain vigilant (1 Peter 5:8, Matthew 26:41). So we fight, relentlessly, constantly.
1 Corinthians 16:13 says, Be on the alert, stand firm in the faith, act like men, be strong.
The Lord didn't leave us defenseless. He gave us armor. We are outfitted from head to toe, and we hold a mighty sword.
and take the helmet of salvation, and the sword of the Spirit, which is the word of God, (Ephesians 6:18)
The sword is specifically the word of God. It is the only offensive weapon in the Christian's armor. The helmet, breastplate, shield, belt, and shoes are defensive.
The sword mentioned in the verse is not a broadsword. It is a sharp dagger, which all soldiers had at hand.

Matthew Henry says,
Those who would prove themselves to have true grace, must aim at all grace; and put on the whole armor of God, which he prepares and bestows. The Christian armor is made to be worn; and there is no putting off our armor till we have done our warfare, and finished our course. (Matthew Henry)Don't let too many days go by without reading the Word. When Jesus was tempted by the Devil, He countered with the word. And the fact that the Ephesians verse distinguishes between the two types of swords, the broadsword v. the dagger and specifically used the word for dagger in this case, means that the the Christian is to wield it with precision. Jesus knew exactly which scriptures to use in reply to the devil. A Christian who knows some scripture but not many isn't going to be an effective soldier nor a good witness.
There is no armor specified for the back, but only for the front of the body; implying that we must never turn our back to the foe (Lu 9:62); our only safety is in resisting ceaselessly (Mt 4:11; Jas 4:7). Jamieson Fausset Brown)Is your Bible in the weeds, metaphorically? Or is it by your side, in your heart, on your mind? Be a good soldier, and have your offensive weapon ready when trials come. They will come. Jesus promised it. And He always keeps His promises.
