This passage plain scares me. These verses serve initially as a reminder to teachers that they a incur “stricter judgement” when wielding the power of the spoken word via the tongue (or typewriter/blog post). Our speech is so difficult to tame or bridle. These verses can serve as a reminder to all of us as to how we can choose to be encouragers or defilers from moment to moment from the same source (our speech). James reminds us how difficult yet important it is to be careful in our speech.
