'Word of Truth' in the Bible

in [speaking] the word of truth, in the power of God; by the weapons of righteousness for the right hand [like holding the sword to attack] and for the left [like holding the shield to defend],

In Him, you also, when you heard the word of truth, the good news of your salvation, and [as a result] believed in Him, were stamped with the seal of the promised Holy Spirit [the One promised by Christ] as owned and protected [by God].

Study and do your best to present yourself to God approved, a workman [tested by trial] who has no reason to be ashamed, accurately handling and skillfully teaching the word of truth.

It was of His own will that He gave us birth [as His children] by the word of truth, so that we would be a kind of first fruits of His creatures [a prime example of what He created to be set apart to Himself—sanctified, made holy for His divine purposes].
