Ephesians 6:17 King James Version (KJV)
And take the helmet of salvation, and the sword of the Spirit, which is the word of God:
I like how the Complete Jewish Bible says it, "And take the helmet of deliverance."
After all, salvation is deliverance. Deliverance from the way the world thinks and does things.
I also find it interesting that the word helmet is used. In Paul's day, a helmet meant a leather cap with studded with metal for extra protection. Often a plume was inserted to identify the soldiers group or division of the military.
How can a helmet of salvation protect our thinking?
Believers are new creations who should not think the way the world thinks. We are told in the Word to not conform to the world's way of doing things but be transformed by the renewing of our minds. The word transform means metamorphosis - a totally changed creature. Transformation is what salvation does for us. Wearing the helmet of salvation is reminding us we are not the same creature we used to be!
When the lies and fears that satan and his evil minions try to speak into your life come, you remember you have a changed mind and you don't agree. Fight back with the knowledge that you have the mind of Christ.
Your helmet of salvation can also identify you as belonging to Christ. You won't look like the world does .I'm not talking about fashion (although the Holy Spirit might well lead you into dressing differently) but you won't be wearing the expressions of the jaded and hopeless if your spirit has been renewed within.
Keep your salvation experience in mind every time you wage war on the enemy. Evil has already lost the war because you belong to Christ. You've got the helmet of deliverance.
