Why do we love?

I don't know if this is God's way of getting my attention. But it sure is working. The past few incidences have made me really think of what I'm doing here. Why am I helping all these people that i don't even know? I thought about it for a pretty long time. And i came to one conclusion. God's love is overflowing so much so that I can't contain it, so i have to share it with others, and from there they will all know that I am God's child. For it is only between me, and God.

35"For I was hungry and you gave me something to eat, I was thirsty and you gave me something to drink, I was a stranger and you invited me in, 36I needed clothes and you clothed me, I was sick and you looked after me, I was in prison and you came to visit me.'

37"Then the righteous will answer him, 'Lord, when did we see you hungry and feed you, or thirsty and give you something to drink? 38When did we see you a stranger and invite you in, or needing clothes and clothe you? 39When did we see you sick or in prison and go to visit you?'

40"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.'

Matthew 25:35-40

34"A new command I give you: Love one another. As I have loved you, so you must love one another. 35By this all men will know that you are my disciples, if you love one another."

John 13:34-35
