God has given Christians spiritual armor described in Ephesians 6 to protect them from Satan's attacks. The armor includes the belt of truth, breastplate of righteousness, shoes of peace, shield of faith, helmet of salvation, and sword of the spirit, which is the word of God. Prayer holds all the armor together. It is important for Christians to put on this armor every day so that they are not weak and can successfully fight against Satan with God's help and promise to be with them in the battle.
