To truly show your love for someone is to respect that person's wish and not do to him what you think might make him happy. For example, my son gives me a nice gift on Father's day. I appreciate that. But I would be so much happier if he would watch some videos I sincerely wish he'd watch instead. In other words, you take into consideration of what your loved one desires. It's the same way to love God. We simply obey him, not doing what we think might please him, which, of course, could turn out to be the same thing, but the motivation is different.
