This is always good advice; advice that I sometimes don’t heed. From the Preacher, as recorded in Ecclesiastes chapter 5:
1 Guard your steps when you go to the house of God. To draw near to listen is better than to offer the sacrifice of fools, for they do not know that they are doing evil. 2 Be not rash with your mouth, nor let your heart be hasty to utter a word before God, for God is in heaven and you are on earth. Therefore let your words be few. 3For a dream comes with much business, and a fool’s voice with many words.
It’s clear what God expects of us; it is a theme that is repeated over and over by the prophets, and by our Lord, who expressed the same concept in Matthew 5:37:
Let what you say be simply ‘Yes’ or ‘No’; anything more than this comes from evil.
This isn’t just a rule for right living; it is what God expects of us. It is among the lessons we take from Scripture, which our faith must encourage us to take to heart.
