Be kind. Show compassion. Perform one act of kindness. You will be blessed as much as, or more than, those you help. It doesn't cost much.
We bought a package of brown paper bags (can be used as a campfire starter--yes, many of our local homeless camp out). In those bags, we put a granola bar or cereal bar, a can of Vienna sausages or potted meat, a bottle of water or a small juice box, a plastic spoon to eat the canned meat, and a piece of candy. Each bag we make costs around $1 or so. It's a part of our tithing that directly helps those that are shunned or ignored.
Blessings and Merry Christmas to each of you. May you be blessed with joy, peace and health.
