Ephesians 4:29 (ESV)
Let no corrupting talk come out of your mouths, but only such as is good for building up, as fits the occasion, that it may give grace to those who hear.
A certain courthouse in Ohio stands in a unique location. Raindrops that fall on the north side of the building go into Lake Ontario and the Gulf of St. Lawrence, while those falling on the south side go into the Mississippi River and the Gulf of Mexico. At precisely the point of the peak of the roof, just a gentle puff of wind can determine the destiny of many raindrops. It will make a difference of more than 2,000 miles as to their final destination. We can see a spiritual application by this. By the smallest deed or choice of words we might set in motion influences that could change the course of others' lives here and now and could also affect their eternal destiny.
Dear Lord, help us watch the words we say and the things we do so that they will build others up and not tear them down. In the Name of Jesus, Amen.
