Kindness means the good things you do for people or individuals. Sharing what you have to others one the act of kindness that matters a lot. Sharing things is good because as you share, God continues to open the way for you.
In my new area we have a lot of beggers, because of my act of kindness I decided to share the little I have with them, let me just I don't share I gave them the little I have, that was just a new student, when I went home, in the straight three curators in this visit that is the work of God.
However, in school, we used to show ourselves acts of kindness. I have a very selfish friend, and when he gives a person his thing, he would rather pure it on the floor, so I will buy we sit down and eat, but he doesn't use give. Because of his selfishness, I disown him as a friend who doesn't have that act of kindness.
Sharing things with people doesn't reduce your resources but helps you come closer to God because when you show that act of kindness, the prayer from the person or people will bring you closer to God.
