This is just a beautiful, simple reminder to be kind to people. It seems like everyone is mean these days. You can barely walk into a store without hearing someone be unkind; either to you or someone else. That grieves the heart of God.
Proverbs 16:24 says, "Gracious words are a honeycomb, sweet to the soul and healing to the bones." I love honey. Imagine the taste of honey, on toast or in tea or something. It's just delicious. Our words should be like that. They should be able to help someone feel better, or provide a little sweetness in someone's day.
Even a simple hello would do. Little things mean a lot sometimes, especially in a world where people have no love for each other. Consider it a witness.
