This is a difficult verse to understand if you do not understand the culture of the law and how dogs and pigs were considered unclean animals. That said I am not inclined to dig into this aspect of this verse. Consider these two verses from Proverbs 16:
Answer not a fool according to his folly, lest you be like him yourself.These verses speak to me about how we must be wise not only in what we say but in who we say it to. The truth of the matter is that fleshly debate and arguments do little to advance the kingdom of God. In the same way, sharing our hearts with foolish people will often break our hearts. Knowing when to share requires discernment.
Answer a fool according to his folly, lest he be wise in his own eyes.
That said, I think that it would be unwise to use this verse to justify silence when we are led to share with another soul. When we are presented by an opportunity to share we must embrace the moment. In times like these we should resist the urge to wax theological and speak from our heads. People need to hear from us in transparent and vulnerable ways.
Not all are fools. Many need Jesus. He is the priceless pearl.
Lord help me to be discerning. Help me to be bold in sharing with others.
