The Whole Armor (Part 1)

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:

Genesis 3:2-4 "And the woman said unto the serpent...God hath said, Ye shall not eat of it, neither shall ye touch it, lest ye die. And the serpent said unto the woman, Ye shall not surely die."

The truth will protect you from lies and doctrinal errors of the enemy. Truth is the undergirding of your spiritual armor. You are to have your loins (your spiritual vital organs) girt (covered) with truth:

Ephesians 6:14 "Stand therefore, having your loins girt about with truth..."

What is the truth?
-Jesus said, "I am the truth."-John 14:6

-The Holy Spirit is the "Spirit of truth.-John 14:17

-God is truth. -Romans 3:4

-God's Word is truth.-Psalms 119:151

-The Gospel is truth.-Colossians 1:5

In the natural world, the breastplate covered the upper body of the warrior to protect vital organs such as his heart, lungs, etc. The spiritual breastplate of righteousness does not refer to your righteousness, but to the covering of the righteousness of Christ:

Philippians 3:9 "And be found in Him, not having mine own righteousness, which is of the law, but that which is through the faith of Christ, the righteousness which is of God by faith."

You do not stand on your own merits. You stand in Christ. You can not face the enemy without the protection of the righteousness of Christ:

2 Corinthians 6:7 "By the word of truth, by the power of God, by the Armor of righteousness on the right hand and on the left."

The righteousness of Christ protects your spiritual "vital organs" from attacks of Satan and from unrighteousness. The breastplate of righteousness must be buckled on to the belt of truth.
