Paul concludes his letter to the Epheisnas with a warning: Satin is working against us. Many of the things that we experience in life are a direct result of the Devil's efforts. he will attach and oppose us at every turn. God has equpied us with an armor that is sufficient: truth, righteousness, peace, faith the spirit, salvation and prayer. The most overlooked and most important part of our reading is that Paul describes all this armor to allow us to stand. He knew that it would take a lot of endurance and perseverance to stand and succeed. His armor is sufficient against any kind of attack. What divine resources we have been given. There is no excuse for failure because God has given us what we need.
In verse 17, Paul tells us to Take the helmet of salvation. Take is a different word in this verse than the one where he said to take the armor of God. In verse 17, take means to receive (as in a gift). The helmet is one of the few pieces of a soldier's equipment that exists to this day. All fighting men have known that protecting the head is critical. Many things about warfare have changed, but the helmet is as important today as it was then. Our heads need protection. The head commands the whole body. An unprotected head (and mind) is open to the attack of the enemy. The devil will attack our minds. He will try to make us forget the goodness of God. He will plant the seeds of discontent. He will work to cloud or judgment of right and wrong. The devil will fight our will to progress and grow.
The devil attacks our mind because he recognizes the potential of our minds. If we have a mind to work, we will work. If we have a mind to pray, we will pray. if we have a mind to praise, we will praise. If the devil can obstruct our mind, he can obstruct our relationship with God. If the devil can tie up our mind, he does not have to tie up our bodies. The only ting that can protect our mind is the salvation that God has provided.
Everyone needs to receive the protection that salvation provides. When God protects the mind, it is not what we have done, but what God has done for us. Salvation is not dependent upon what I have done, but what HE has done. The devil will try to convince us that we are not saved; that salvation may work for other people, but not us. The helmet of salvation will protect our minds from these lies.
