Ephesians 6:14-17 New International Version
“Stand firm then, with the belt of truth buckled around your waist, with the breastplate of righteousness in place, and with your feet fitted with the readiness that comes from the gospel of peace. In addition to all this, take up the shield of faith, with which you can extinguish all the flaming arrows of the evil one. Take the helmet of salvation and the sword of the Spirit, which is the word of God.”
All the defensive parts of the armor were girded close to their bodies of the soldiers using an ornamented belt. In the same way, Christian warriors wearing the armor of God should bind salvation, faith, righteousness and peace unto themselves using the Truth. 
A soldier would hang small food items and liquids for nourishment and hang his weapon from the belt as well. It is also meant to protect a most vulnerable area, our pelvic region.
The redirection of thought and distraction are ways our enemy, the devil, can distract us and cause us to fall. We must “gird our loins” as the King James translation puts it, to protect ourselves from attack. Feast on the truth of God and do not entertain that which is worldly or displeasing to God. To do so leaves you vulnerable to attack. We are in a spiritual war and will lose on a personal level if we are not alert and girded properly with His truth. Seek the wisdom of God to direct you in the ways that you should go daily. Immerse yourself in His ways. Study how to be like Him more each day. Don’t miss the opportunity to do something great for the kingdom. God wants to use you. Be ready. Until next time, walk with the King and be a blessing!
