Ephesians 6:10-17 (King James Version)
"10Finally, my brethren, be strong in the Lord, and in the power of his might.
11Put on the whole armour of God, that ye may be able to stand against the wiles of the devil.
12For we wrestle not against flesh and blood, but against principalities, against powers, against the rulers of the darkness of this world, against spiritual wickedness in high places.
13Wherefore take unto you the whole armour of God, that ye may be able to withstand in the evil day, and having done all, to stand.
14Stand therefore, having your loins girt about with truth, and having on the breastplate of righteousness;
15And your feet shod with the preparation of the gospel of peace;
16Above all, taking the shield of faith, wherewith ye shall be able to quench all the fiery darts of the wicked.
17And take the helmet of salvation, and the sword of the Spirit, which is the word of God:."Ephesians 6:18 (King James Version)"18Praying always with all prayer and supplication in the Spirit, and watching thereunto with all perseverance and supplication for all saints;"
Before the salvation, there is no Armor of God in men. After a man gets saved, he receives the Helmet of Salvation that shows his salvation through Lord Jesus Christ. As long as a man is telling the truth, he has the Belt of Truth on his Armor of God. This man is so faithful in Lord and protects himself from the temptation, it means this man has a Sheld of Faith. Breastplate of Righteousness should be put on him if he does the right things everyday like respecting each other, loving each other, obeying God's commandents, and holy actions or deeds. The Word of God can be used to prevent the temptation, and a man can have the Sword of the Spirit. This sword is the God's Words that can destory the evil spirits or things like using the Word of God from the Bible to block the temptation of lust or addicting the shapes of women. The final part of Armor of God is the Gospel of Peace (boot of gospel). Armor of God carries the gospel boot (Gospel of Peace) by spreading the good news of Jesus Christ to everyone. And the important part of Armor of God is pray. WIthout pray, the Armor of God includes Helmet of Salvation, Breastplate of Righteousness, Sheild of Faith, Sword of the Spirit, Belt of Truth, and Gospel of Peace, will all be useless and no good. Pray is needed to support these things in Armor of God, so it can fight the evils better with pray. God can help anyone who prays with Armor of God on to fight the spiritual battle (good v.s. evil).
