Found in Ephesians 6:13-17
Belt of truth, buckled around your waist! Know the truth and that it holds your armor in place, and remember to live by it, its close to some areas that are important!
Breastplate of righteousness- We are the righteousness of God in Christ Jesus! Bring Glory to God!
Feet fitted with readiness that comes of gospel of peace (Boots of the Gospel)- We will step on snakes and scorpions as we spread the gospel, know that we are protected in our walk!
Shield of faith- which can extinguish all the flaming arrows of the evil one! No weapon forged against us shall prosper!
Helmet of salvation- on our head. We know we are saved, and we are protected from the lies of the enemy that would try to hold us in condemnation! we have God's grace, and we are loved and saved by his precious blood!
Sword of the Spirit- which is the word of God! Our armor protects us from the enemy, but if we want to ATTACK and take back ground for the kingdom of God, we need a big sword. We can make our swords big by getting into the word!
Verse 18 is also very important

to pray in the Spirit! Praying in the Spirit is the prefect prayer language. We surrender ourselves to the Holy Spirit, and declare that He knows best, and though we may not know, we put our faith in Him to pray for us to God. It is the perfect prayer language, and can communicate things that English or any other language cannot. Also, the devil cannot understand this language, because it is Holy! So "pray in the Spirit on all occasions with all kinds of prayers and requests."
