My favorite scripture verse, doesn't come from the Bible, it comes from the Book of Mormon. This scripture is my favorite, and I try daily to live to this verse.
Mosiah 2:17-And behold, I tell you these things that ye may learn wisdom; that ye may learn that when ye are in the service of your fellow beings ye are only in the service of your God.
I feel so wonderful about myself when I am serving others. Its a natural high for me!
