Blue Like Jazz

If you don't love somebody, it gets annoying when they tell you what to do or what to feel. When you love them you get pleasure from their pleasure, and it makes it easy to serve.
(Blue Like Jazz, Don Miller, p. 14)

I just started reading this book and so far I'm really liking it. Miller truly hits home. Much of what he has gone through or has thought/realized resonates with a lot of what I have experienced and have realized myself but even more so with what I have had trouble figuring out. The part he wrote about how when you love someone, you get pleasure from their pleasure, strucked a huge chord with me. I read that sentence over and over again and it has been continuously repeating in my head the past few days.

I realize that I don't really know what love is. I don't know what it means to truly love. I think I take love very lightly. I tell people I love them but what does it really mean? More importantly, I tell my Heavenly Father that I love him but what does that really mean?

What does God take pleasure in? Do I take pleasure in His pleasures? In His joys? Do I really love Him?
