To communicate effectively is a skill, almost an art. Our words can be as sweet as honey or as sharp as a two-edged sword; the power of life and death is in the tongue. Many secular books have been written about effective communication, and many passages in Scripture covers the topic of the tongue and the effects of the words spoken by it. Being a good communicator is important as most of us interact with others via the internet and other social media. The written word is easily misunderstood, for there are no emotions or body language to verify the message. We are therefor to think before we speak or type. Each of us is, effectively, the teacher of our neighbors and our brothers. This will remain so according to Jeremiah 31, until the new covenant is fully in effect.
