Kindness can become its own motive. We are made kind by being kind.
You don't need a reason to help someone else. Find a way to be kind to EVERYONE you meet today. It will not only change the way you feel about yourself, it will change you.
But love your enemies, and do good, and lend, expecting nothing in return, and your reward will be great, and you will be sons of the Most High, for he is kind to the ungrateful and the evil.
