What does the Bible say about giving holy things to dogs?

In Matthew 7:6, Jesus instructs His followers not to give what is holy to dogs nor cast pearls before swine. This metaphor highlights the importance of discernment in sharing the gospel. The holy nature of the gospel signifies that it is not intended for everyone indiscriminately, especially those who show contempt for it. Just as dogs and swine do not appreciate valuable items, so too are there individuals whose hearts are hardened against the truth of God's word.

The injunction finds its roots in Proverbs 9:7-9, which emphasizes the futility of reproving the scornful while encouraging instruction for the wise. The gospel message is precious and should be shared with those who are receptive, primarily the humble and broken-hearted, as articulated in Isaiah 61:1. The gospel is to be audibly proclaimed to all, but discernment is needed to recognize those who are truly in need of its hope.
