Introduction: Given the fact that you have called to be engaged in the spiritual battle for truth, God has provided you with the necessary weaponry and armor to successfully engage the enemy. We have looked at the Belt of Truth, the Breastplate of Righteousness, the Shoes of the Gospel of Peace, and the Shield of Faith. Today we will consider the last two pieces God has made available to you as a Christian soldier – the Helmet of Salvation and the Sword of the Spirit.
I. Helmet of Salvation – verse 17
A. The helmet was the most noticeable piece of Roman armor. Often they were ornate, being intricately decorated, and plumed with brightly dyed feathers or horsehair. Parade dress helmets were made with course horsehair plumes that would extend to the waist. The Roman army helmet was usually made of bronze, although iron and leather were also used on occasion. They were designed so that blows to the head from a sword hammer or ax could not pierce. To protect the sides of the face, “cheek–pieces”, hinged to each side, hung down and were secured with leather straps under the chin. A “shelf” on the back of the helmet protected the neck and shoulders from arrows that fell from above. At some point in the first century a “bill” was added to the front of the helmet along with bronze coverings above the ears. A leather liner on the inside made the heavy helmet a little more bearable.
B. The two most vulnerable spots on a soldier are the heart and the head. The breastplate protected the heart. The helmet – the head. The head of the soldier needed protecting, as on it the deadliest strokes might fall, and it is the head that commands the whole body. The head is the seat of the mind
C. Satan’s focus of attacks is either the heart or the mind. Satan is the master of mind games. He seeks to captivate our minds and in so doing poison our minds weakening our faith and making us ineffective.
D. He will attack our minds with deception, distraction, distortion, discouragement and divisiveness.
G. We need to protect our minds.
H. To protect us God has given us the helmet of salvation.
J. This does not refer to being saved. That’s already happened if you are in Christ’s army.
K. There are three aspects to salvation, three tenses, past, present and future. These are simply defined in this way: the past frees us from the penalty of sin; the present tense is freedom from the power of sin; and the future will deliver us from the presence of sin.
L. 1 Thessalonians 5:8-9 (quickview)  “But let us who are of the day be sober, putting on the breastplate of faith and love, and as a helmet the hope of salvation. For God did not appoint us to wrath, but to obtain salvation through our Lord Jesus Christ.”
