“Do not give what is holy to dogs, and do not throw your pearls before swine, or they will trample them under their feet, and turn and tear you to pieces” (Matthew 7:6).
A retainer is that which holds something in place. For example, an orthodontic device that holds one’s teeth in place. Hopefully, the gospel of God’s grace is a retainer that holds our heart and tongue in place. In the context of not judging others (7:1-5), Jesus now emphasizes that this is one of the things that separates and makes us stand out from the unbelieving world. In a world that has stereotyped Christ followers as self-righteous, critical and judgmental, we cannot afford to throw away that which makes us unique. Fill your world with grace and mercy.
