“Who wears armour in times of peace? Armour is designed for those going into battle! Do not think simply putting on the grace of God will frighten the enemy away. He is not impressed by a show of force. On the contrary, the very sight of God’s armour upon your back is like waving a red flag at Satan. So to have it on for show is not enough; you must have it securely fastened at every point.
Satan is not challenging you to a mock battle; this war is a life-or-death struggle. If you do not believe me, look what he has done with God’s servants in times past. Charging full speed ahead at many a dear saint, he has battered their armour until the grace of God in them was almost unrecognizable. All this he does when he catches a saint off guard.
Do you remember what happened to Jacob when he unbuckled his girdle of truth and sincerity, and used a trick to get his father’s blessing? He got the blessing all right, but he also was repaid in kind when Laban switched Leah for Rachel. Think how much suffering he might have saved himself by keeping his whole suit of armour in place!
What about David? Oh, the battering he took by removing his breastplate of righteousness in the matter of Uriah! He sustained a dreadful wound, being shot right through the heart. And Jonah, when God wanted to send him to Nineveh, got caught without his shoes on. By that I mean he lacked the preparation and readiness with which his mind should have been shod, to have gone at the first call. Then there was poor Hezekiah. He had his helmet of hope knocked askew and so badly dented that he cried, ”I shall not see the Lord…in the land of the living” (Isa.38:11). Even Abraham had fits of unbelief and distrustful qualms that crept in at some rusty spots in his graces.
This war is a spiritual holocaust. Either you destroy the power of Satan in your life by putting on the whole armour of God and keeping it on, or Satan will destroy you.”
Ephesians 6:13-17 Wherefore take unto you the whole armour of God, that ye may be able to withstand in the evil day, and having done all, to stand. Stand therefore, having your loins girt about with truth, and having on the breastplate of righteousness; And your feet shod with the preparation of the gospel of peace; Above all, taking the shield of faith, wherewith ye shall be able to quench all the fiery darts of the wicked. And take the helmet of salvation, and the sword of the Spirit, which is the word of God:
