Proverbs 16:2 (ERV)
Kind words are like honey; they are easy to accept and good for your health.
When you talk, you should always be kind and wise. Then you will be able to answer everyone in the way you should.
Saying the right thing at the right time is like a golden apple in a silver setting.
A quick search of the bible can bring up a lot of advice on how to speak kindly. Words often ignored in the name of whatever 'crusade we' are embarking on.
