Matthew 7:6 KJV
6 Give not that which is holy unto the dogs, neither cast ye your pearls before swine, lest they trample them under their feet, and turn again and rend you.
I have to admit, this verse isn't clear to me. I can understand that we are not to "waste" our possessions, time, etc. on undeserving opportunities, but there has to be more to it that just that.
Do you have any insights? Please share!
