Truth is a crucial piece in the believer’s armour, girding the loins and, as such, freeing a man from life's entanglements.
It is imperative that men speak the truth, for “he that speaketh the truth sheweth forth righteousness,” and his lip “shall be established for ever.”
A basic definition of communication involves making things common. When we speak to others, we express what is in our minds and hearts making those thoughts common with others. The Bible warns the believer in Ephesians 4:29 to “Let no corrupt communication proceed out of your mouth, but that which is good to the use of edifying, that it may minister grace unto the hearers.” The words that come out of our mouths should edify or build up others, not demean and degrade them. They should be strengthened by what we say. Keep in mind that corrupt communications weaken the believer (1 Corinthians 15:33). This is why Christians are instructed to put off all “filthy communication” (Colossians 3:8).
