The helmet protects the head—perhaps the most vital part of the body since it is the seat of thought and the mind. When we have a sure knowledge of our salvation, we will not be moved by Satan’s deceptions. When we are certain that we are in Christ with our sins forgiven, we will have a peace that nothing can disturb.  The sword of the spirit is the only weapon of offense listed in the armor of God. God’s Word—the Bible—is described as “living and powerful, and sharper than any two-edged sword” (Hebrews 4:12). Jesus used this weapon when Satan tempted Him in the wilderness. To each of Satan’s efforts to lead Him into sin, Jesus replied, “it is written. . . “ and proceeded to quote Scripture to destroy Satan’s temptations. The sword of God’s Word both protects us and destroys our enemy—the devil and his temptations.

The truth of salvation changes everything here and eternally.

• Use the example of Jesus in the wilderness to show the power of God’s word in the fight against Satan.
• We can receive tremendous hope and comfort by focusing on the incredible sacrifice Christ gave to save us and the amazing Kingdom that is the goal of our salvation. This hope works like a helmet to protect our minds from the discouragement and despair in this world. John 17:15-16
• Without the helmet of salvation, we will be unprotected from the "cares of this world" that bombard our thoughts and feelings. Imagine not knowing what the future ultimately holds. The worries and problems produced by living in this world would overwhelm us!
• Psalm 27:1
• The Lord is my light and my salvation; whom shall I fear? The Lord is the strength of my life; of whom shall I be afraid?
• With the helmet securely fastened, we can have the same confidence that Paul did that "the sufferings of this present time are not worthy to be compared with the glory which shall be revealed in us" (Romans 8:18). We understand that it doesn't matter what happens to us now. No matter what trials we face, we know that at the end of it all waits God's Kingdom and an eternity of His perfect reign—and what could be better than that
• The Romans relied in part on assailing their enemy from a distance with javelins and darts, but God does not give us that option as Christian soldiers. If we were able to fight our battles from a distance, we would never experience an actual trial.
• Reading 2 Hebrews 4:12-16  Double edged sword and Jesus as high priest, Could do something focused on salvation from a Gospel
• John 17:15-16
• Why a sword?
• Hebrews 4:12
• For the word of God is living and powerful, and sharper than any two-edged sword, piercing even to the division of soul and spirit, and of joints and marrow, and is a discerner of the thoughts and intents of the heart.
• The all-powerful sword of the living God is able to cut through every defense our enemy can raise—down to the very division of bone and marrow. When wielded by a servant of God, nothing can withstand its ability to cut straight to the core of a matter and uncover the truth. As soldiers in God's army, it is our responsibility and duty to use His Word to discern the truth and then follow it. When God's Word shows us something wrong in ourselves, we can use this spiritual weapon to "surgically" remove the offending thoughts and actions (2 Corinthians 10:4-5).
• Unlike all other pieces of the armor of God, which are solely defensive, the sword is uniquely suited for both defensive and offensive roles. A solid defense is invaluable, but the sword is the only way we can complete the work we have been given to do.
• Notice that Jesus Christ used the Bible to counter Satan's attacks (Matthew 4:4, 7, 10). We must also learn to live "by every word that proceeds from the mouth of God" (Matthew 4:4).
