It’s a battle cry to me. Put on the most secure item of wear on your feet, your boots and lace them up. The boot is, your protection as the feet have nerve endings associated with your bodies sensitivities such as pain, temperature and balance. Then your backpack will carry the essentials needed for battle. It’s spiritual warfare preparation! What will be in your Backpack? The Word of God is first…! The elements of God’s Armor! The Breastplate of righteousness,The Belt of truth, shoes of peace, your shield of Faith, and the helmet of Salvation, Sword of the Spirit, and Constant Prayer.
