"For out of the overflow of the heart the mouth speaks." Matthew 12:34b
Whenever we let love lead us in what we say to one another, our words will always be edifying, even if the words are those of correction. Correction from a heart of love, (truly 'love' and not merely hiding beneath the facade of 'love' in order to speak hurtfully), will always lift a burden from the other person and bring freedom, not lay upon them a heavy weight of condemnation.
Let's guard our words in such a way that we speak life to one another!
