“And the tongue is a fire, a world of iniquity: so is the tongue among our members, that it defileth the whole body, and setteth on fire the course of nature; and it is set on fire of hell.” - James 3:6.
One of the factors that separate people is the way they use words. We should be very careful in our choice of words, especially when we are angry, lest we injure our neighbour. The Bible says: “An hypocrite with his mouth destroyeth his neighbour: but through knowledge shall the just be delivered.” (Proverbs 11:9) Words are not only for communication, they can act as weapons which can hurt more than physical weapons. Those who are hurt that way may stop believing in humanity and their outlook on life may change forever. Words can hurt or heal, build up or tear down, comfort or curse. We should use our tongues to build good relationships to the glory of God. “A wholesome tongue is a tree of life: but perverseness therein is a breach in the spirit.” (Proverbs 15:4) St. Paul admonished: “Let your speech be alway with grace, seasoned with salt, that ye may know how ye ought to answer every man.” - Colossians 4:6.
