Speak only when God gives a word

I'm reading in Ezekiel now and I was struck reading about Ezekiel only speaking when God gave him a word.  Now, that would be hard in the world we live now to have any relationships.  However, what if we only posted on Social Media when God gives us a word?  Can you imagine how much more civil it would be?  What if Christians set the example of love and grace instead of blabbing all of our complaints all over the web?
