The first piece of armor to be buckled on is the girdle or Belt of Truth. In the natural world, a suit of armor was attached to the belt which held the other pieces of armor in place. The truth of God's Word is the spiritual belt to which all other pieces of armor are attached.
Satan's first attack on man was on truth (Gen. 3:2-4).
The Belt of Truth will protect you from lies and doctrinal error of the
enemy. Satan's first attack was deception (coming against the Belt of
Truth), and man's first response after sin was hiding, denial, and
blame-shifting (Gen. 3:9-13). Sound familiar? We still do the same thing
today. It is painful to see the truth about ourselves. We blame our
sinful or wrong reactions to difficult circumstances, depressed economy,
an unfaithful spouse, an aggravating spouse, a rebellious child, a
coworker or boss, a church member,or anything or anyone other than
ourselves. We need to own up to our own faults without excuses and
without blaming, bring them to God, and confess them honestly before
Him. Get your Belt of Truth back on, tighten it up, and stand firm

Another way of looking at the Girdle:
A Roman soldier would need a girdle or belt as part of his equipment. Remember that in those days, a man's clothing (as well as a woman's) was usually a loose garment that came at least to the knees. When a Roman soldier was required to do something active, such as fight or use his weapons, he would need to take care of that loose garment. If he did not, it would hinder his movements and prevent him from using the rest of his equipment effectively.
The first thing he had to do before battle was to tie his girdle (belt) tightly around his waist in such a way that the tunic (loose garment) no longer flapped freely and could not hinder his movements. This was essential, and it was the basis for everything else in battle. That is why Paul mentioned it first.
The actual meaning of the word "truth" means candor, sincerity, and truthfulness. In Ephesians 6:14 it refers to the subjective, practical application of openness and honesty in all things with God and people.
As religious people, we are often full of hypocrisy, sham or facade. To be blunt, "fake" or "shallow". Many things we say and do are not really meant, but we say them only because they sound good. We are good at using religious cliches and words of insincerity.
There are things we do, not to please God or because we really want to do them, but to please or impress other people. That gets in our way and prevents us from doing what God asks us to do. It also hinders or prevents us from using the other spiritual warfare items of our equipment against the enemy.
