Words can be a weapon or a tool. They can be used to tear down or build up. They can be used to destroy or defend. I, and many others, have been hurt by the words of others. Whether purposefully or accidentally. I have also hurt people with my words both purposefully and accidentally.
He that covereth a transgression seeketh love; but he that repeateth a matter separateth very friends. – Proverbs 17:9
Let your speech be always with grace, seasoned with salt, that ye may know how ye ought to answer every man. – Colossians 4:6
Those are just two out of many verses that the Bible has talking about your words and how you should use them. We need to be careful how we use our words. I’ve watched people be torn down by the words of others. Words spoken directly to them and words spoken “in secret” about them. As Christians, who are to be followers of Christ, our words should be words of truth spoken in love.
But speaking the truth in love, may grow up into him in all things, which is the head, even Christ: – Ephesians 4:15
Set a watch, O Lord, before my mouth; keep the door of my lips. – Psalms 141:3
