Serving others is a way of bringing peace into the world. When you help your brothers and sisters in humanity you bring them into a place where they can help others too and the cycle keeps on going. If everyone serves then the load is lighter and the work gets done faster. In scripture it says the generous will themselves be blessed, for they share their food with the poor.
Sharing what you have by giving of your time and talents is a great thing to do for others and the world. Doing for others means doing for yourself. There’s lots of good in being there for others and working to make the world a better place.
