Acts of kindness are greater than charity in three ways:
1. Charity is done with one's money, while kindness may be done with one's money or with one's person (Example: visiting a sick person)
2. Charity is given only to the poor, while kindness may be done for both the poor and the rich (Example: spending time and comforting a mourner or depressed person)
3. Charity is given only to the living, while kindness may be shown to both the living and the dead (Example: arranging the burial of a person who died indigent)
