I'm speaking at a girls' Bible study about love and I need help?

I'm going to speak at a girls' Bible study about love but I don't know what to say. The topic this week is love and I don't know whether I should talk about brotherly/friendship love or how much God and Christ love us and how that can affect our lives. What do you think I should do and please give me some useful information that I could say at the Bible sudy. Thanks for your time and information. Btw this is my first time ever speaking in front of an audience so I'm nervous.
