First Nephi 5:9

And it came to pass that they did rejoice exceedingly, and did offer sacrifice and burnt offerings unto the Lord; and they gave thanks unto the God of Israel.

When we are thankful and full of gratitude, we are more inclined to sacrifice from our abundance. It can also work the other way: when we sacrifice from our abundance, we can grow more thankful for what we have. If we are missing the spirit of gratitude in our life, a willing sacrifice will bring us the sense of thankfulness we may be missing.
