Sacrifice?

Recently I received an email from a very good friend.  She referred to our Mission Service as "great sacrifice".  Her words made me think and ponder.  Was it a sacrifice to serve these past 3 years?   I started typing out a reply and these were my words.   "Sacrifice?... yes, I guess in a family, business and physical sense, it is a sacrifice .  Spiritually however it is a huge blessing.  There is no sacrifice. I feel now looking at our service that The Lord allowed us to experience something, otherwise would have never come our way.  There are no regrets when you serve the Lord. The Blessings are overflowing"
