“Stand therefore, having girded your waist with truth,” (Eph 6:14)
Truth is the belt that holds all the other pieces of armor in place. First, it refers to the truths of the Bible as opposed to the lies of Satan. The love of God, salvation through faith in Jesus Christ, the Second Coming, grace through Christ set us free, “Ye shall know the truth, and the truth shall make you free” (John 8:42).
Secondly, by serving as a belt, truth holds together the full armor of God. It is a Christian’s commitment to truth.
