The homily started with a story, one experience of the priest when he hosted a mass, he saw a lady who got some bill on her wallet during the collection but the priest noticed that she puts back the bills and took some coins.
Sharing according to wikipedia is the joint use of a resource or space. In its narrow sense, it refers to joint or alternating use of an inherently finite good, such as a common pasture or a shared residence. It is also the process of dividing and distributing. Apart from obvious instances, which we can observe in human activity, we can also find many examples of this happening naturally in nature. When an organism takes in nutrition or oxygen for instance, its internal organs are designed to divide and distribute the energy has taken in, to supply parts of its body that needs it. Flowers divide and distribute their seeds. In a broader sense, it can also include the free granting of use rights to a good that is capable of being treated as a nonrival good, such as information. Still more loosely, “sharing” can actually mean giving something as an outright gift: for example, to “share” one’s food really means to give some of it as a gift.
On the other hand giving in general is an act or of to make a present, to grant or bestow a formal action, so giving of something you have may vary of sharing by heart or you just obliged to do it because you needed to, maybe because you are a politician candidate and you should set a good image and that is to give something that you have. Love to your fellowmen could also be the best example of sharing, even you are just an ordinary human being living in this world or community it is because you love them thus you are sharing what you have for them, a little sacrifice, that is one way of showing your love.
There is this commercial in TV, I just forgot what they had endorsed but the sacrifice of the wife to show her love to her family was a thing that anyone could easily remember, the wife in the commercial brought some things for her family and when the husband asks her what does she got for herself, she said nothing, but she is happy that she was able to make them happy by the things she gave to them. Love always had a profound meaning, you can never measure it, you may never understand why a person have to offer sacrifice to show that person that he or she love him or her so.
One thing I learned from the homily was Love is not a love without sacrifice and giving is not giving unless you shared it by heart.
