The Helmet of salvation is God's protection for you against the stones of darkness that would be hurled at you. It is to protect the members of your head like the ear. Are you saved? Are you sure? The confidence you gave in your salvation is so important lest the enemy will attack your salvation. You will end up feeling so not saved. And then he can attack you. Work out your own salvation with fear and trembling (work and bring out the salvation in you so all men would know that you are saved. The Word on the other hand is to help you defend against the person of the devil, to slay him out. When Satan came to Jesus after he had fasted forty days and forty night, He (Jesus) responded "it is written". After three cuts of the sword of the Spirit the devil left him. Precious One, you will need your sword and your helmet at all times to triumph in every situation every day. God bless you
