When David goes out to face Goliath, he is offered another man’s armor. It’s just too big and doesn’t fit. So he goes with what he’s accustomed to – a slingshot and five smooth stones.
In Ephesians 6 God explains some armor that is fitted just right for you. The question is do you put it on, do you wear it, and are the pieces big enough for the battles you fight? Think about it. If your faith is small and you are going to battle, it may seem like you are holding a Tupperware lid as your “shield of faith”. How many flaming arrows are you going to extinguish with that?
Your faith must be strong and wide, and ready to extinguishing the flaming arrows. God knows that. Do you? Or do you go out unprepared and hope for the best? How big is your faith? What is your faith made of?
You are fighting battles which are not tiny – “we do not wrestle against flesh and blood, but against the rulers, against the authorities, against the cosmic powers over this present darkness, against the spiritual forces of evil in the heavenly places. Therefore, take up the whole armor of God, that you may be able to withstand in the evil day.” If your faith is small, your battles will be too. And there will be losses. There will be more loss than need be.
The man who has a son possessed by demons who cause him to convulse horribly for years asks Jesus to heal him. At one point the man says, “help my unbelief.” He knows his faith is small. The word used here is the opposite of faith. He says help my unfaithfulness. Help me where I don’t believe. Help me to have more faith. In Greek, the same word is used for belief and faith depending on whether it is a noun or a verb. Is your faith a verb? Is it active and growing?
Don’t go into battle with tiny armor. Search God’s heart and His Word and find how you can have the all parts of the armor necessary, and growing, to fight the battles He has for you.
