i have lived by these words for years, but maybe not fully. some friends of mine recently took a couple of folks in. like to live with them. if a man knocks at your door for a loaf of bread....don't tell him to come back later....he's knocking 'cause he NEEDS a loaf of bread....why else would he ask. Get him a loaf of bread and if you blessed to have some milk---offer him that while you are at it.
