I used to think people complained because they had a lot of problems. But I have come to realize that they have problems because they complain. Complaining doesn’t change anything or make situations better. It amplifies frustration, spreads discontent and discord (which God hates - Prov 6:16-19), and can invoke an invitation for the destroyer to cause havoc with our lives.
How important it is that believers guard the words of their mouth! The scriptures tell us that our words are literally the basis for whether we are justified or condemned. Realizing this, we should eradicate negative words, griping, or grumbling, and fill our mouth with praise and thanksgiving!
“But I say to you that for every idle word men may speak, they will give account of it in the day of judgment. For by your words you will be justified, and by your words you will be condemned” (Matt. 12:36-37).
