What does the Bible say about casting pearls before swine?

In Matthew 7:6, Jesus teaches that we should not give what is holy to dogs or cast pearls before swine. This verse highlights the gravity of sharing sacred truths with those who may not appreciate them. However, it does not suggest that we should withhold the gospel from people who appear unworthy or sinful. Instead, it emphasizes the importance of discerning when to engage and when to move on, without neglecting our duty to proclaim the message of Christ. Even those who might initially reject or trample on these truths can be transformed by God's grace.
