God has really been talking to me about Love lately

I guess thats why my site is named what it is!
I was talking with my "mama" Martha, who is all alone and in Oklahoma and we were talking about a preacher who was doing a teaching series on love. She doesn't get out hardly if at all so she lives on Christian cassette tapes, Christain books and Christian TV.
It just struck me as so funny that Christians need to be TAUGHT love....I mean they say they know Jesus...if they did then they would know how to LOVE a human being! Love is giving and caring and sometimes giving to a point it is sacrificial in your own personal life. Wether that sacrifice is financial, time, etc.
How hard is it to love someone?
I know loving your enemy is tough, but God has really taught me alot about that too. It just strikes me as funny is all.
