In the same way that my friends had to believe in the TRUTH of the information that they gathered concerning the weather, it is vital for us to put our trust in the Biblical TRUTHS provided to us in God's Word. Interestingly, the first piece of God's armor is the Belt of Truth. I am convinced that it is addressed first because of its importance.
The Belt of Truth is symbolic of the practice in which a Roman soldier secured with a belt his lion cloth, his undergarment (similar to a baggy shirt), and his outer tunic to provide for better mobility during battle. If he would not have done so, his movements could have been hindered in the heat of battle - interfering with his ability to fight the enemy. He would not have been properly equipped to go into battle.
In order to defeat the enemy who is always prowling around our lives poised to attack, I once read that we must "tuck our lives under the belt of God's TRUTH, His Word." We must equip ourselves for battle by tightly securing our thoughts, desires, and actions so that they line up with His Will - His Word.
The Greek word that was translated "truth" was "aletheia". One definition of this word is "the truth as taught in the Christian religion." Ephesians 4:15 details the importance of embracing God's truth "....speaking the truth in love, we will in all things grow up into Him who is the Head, that is, Christ."
My challenge to you today is to securely "gird" God's Word around your life. In John 8:32, Jesus states "Then you will know the truth, and the truth will set you free." The Belt of Truth keeps us secure in Christ and provides the foundation for the other pieces of armor.
