In Ephesians, truth is specifically connected to Jesus Christ. It is, at its core, the veritable content of the good news of God’s salvation by grace given through Christ. Thus, the belt of truth is closely related to “the gospel of peace” (Ephesians 6:15) and “the helmet of salvation” (Ephesians 6:17). But when we think of putting on God’s truth, we rightly infer that this includes more than merely the good news of Christ. We put on the belt of truth whenever we speak and live the truth.
