“A fool uttereth all his mind: but a wise [man] keepeth it in till afterwards (11).”
“Seest thou a man [that is] hasty in his words? [there is] more hope of a fool than of him (20).”
A very important part of our sanctification is learning how to speak with wisdom, both in content and form (God cares what, how, and when we speak). Our speech is part of us, and it will be transformed through the sanctifying work of the Holy Spirit.
Speaking is an art, but speaking wise counsel at the appropriate time is an even greater art. The Lord, however, is gracious, and readily provides instruction; the Lord teaches us what, how, and when to speak through Scripture, prayer, worship, and the Holy Spirit.
