It is vital to protect your head. But only certain helmets will do the job. It will not do you any good to wear a batting helmet while playing football. A plastic construction helmet will not save you in the trenches of war. We must not only have protective headwear, it must be the right headwear. Paul tells us to put on a specific helmet, the helmet of salvation. This sermon discusses what that it and how it effectively protects and secures.
