'Fruit' of the spirit, 'gift' of the spirit, both are used. They have a slightly different connotation, but to me each suggests an offering from the universal spirit to the individual spirit residing in each one of us.
Now, about peace. When I consider world peace and peace among groups of people, it all seems extremely complex and unattainable. Peace within myself and peace, however, I can strive for more easily. I am reminded of the song, "Let there be peace on earth and let it begin with me." Surely a little piece of peace can happen in my little world if I give it a try.
Really, do it!
