(11) Put on the whole armour of God, that ye may be able to stand against the wiles of the devil.
(12) For 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.
(13) Wherefore 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.
(14) Stand therefore, having your loins girt about with truth, and having on the breastplate of righteousness;
Put on the armor of God . . . take unto you the whole armor of God . . . now STAND.
The first part of armor to help us stand is truth; girding (gird all around, fasten one's belt) ourselves with truth.

-Man can deceive himself to believe something that is not God's truth - they can change God's truth in their minds.
"Wherefore God also gave them up to uncleanness through the lusts of their own hearts, to dishonour their own bodies between themselves: Who changed the truth of God into a lie, and worshipped and served the creature more than the Creator, who is blessed for ever. Amen." (Romans 1:24-25)

Even believers can deny God's truth and ignore it. To do so is only opening our lives to a direct attack of satan. It is so very vital for the believer to be rooted and grounded in the truth. How can we use the Sword of Truth if we do not even know the truth? I don't believe there is any "coincidence" that truth is the very first weapon mentioned. The first step of the believer should be to read God's truth, study God's truth, seek God's truth, and follow God's truth. By doing so, they are putting on the first weapon in their armor.
