Who we are to care for:
"Then the righteous will answer him, 'Lord, when did we see you hungry and feed you, or thirsty and give you something to drink? 38 When did we see you a stranger and invite you in, or needing clothes and clothe you? When did we see you sick or in prison and go to visit you?' "The King will reply, 'I tell you the truth, whatever you did for one of the least of these brothers of mine, you did for me.'
Hebrews 13:2-32 Do not forget to entertain strangers, for by so doing some people have entertained angels without knowing it. 3 Remember those in prison as if you were their fellow prisoners, and those who are mistreated as if you yourselves were suffering.
Religion that God our Father accepts as pure and faultless is this: to look after orphans and widows in their distress and to keep oneself from being polluted by the world.
