For out of the overflow of his heart his mouth speaks.
Matthew 6:45b
The Holy Spirit reminded me of this verse the other day, after a gentle reprimand by my husband, when I took credit for something God clearly did all by Himself. I immediately repented of the apparent pride in my heart. In the same way, as mothers we can use this verse to speak to the hearts of our children. If they're complaining, whining, throwing a fit, gossipping, speaking bad about someone they know, or being a tattletale, we can tell them that our words show us what's really going on in our hearts. If we're to have hearts the glorify God, then we must pay attention to the words we speak, carefully watching our tongues.
