Be generosity and share with others

Genesis 18:1-15
Abraham served three men standing nearby with food and drink. Now that you have come to your servant, let me get you something to eat, so you can be refreshed and then go on your way.
Is anything too hard for the Lord? I will return to you at the appointed time next year and Sarah will have a son.
Abram welcomed a stranger and, all unknowingly, took the Lord himself into his home.
Why?
The lavish welcome and provision (despite the inconvenience of the visitors' arrival during the midday siesta) are typical of hospitality amongst nomadic游牧 desert people even today. The 'morsel一口 of bread' offered to the guests turns out to be a meal of fresh cakes, curds凝乳 and milk, and the best veal小牛肉.
The words 'Is anything too hard for the Lord?' reveal the visitor's true identity, and Sarah's incredulous laughter changes to fear.
Generosity is one of good behavior to every Christian.
How?
Is anything too hard for the Lord? Be generosity, give to and share with others.
