In light of eternity, the years we live on this earth are relatively small. Therefore we should want our life to count.
As John Piper says in his book, Don't Waste Your Life - "God created us to live with a single passion to joyfully display his supreme excellence in all the spheres of life. The wasted life is the life without this passion. God calls us to pray and think and dream and plan and work not to be made much of, but to make much of him in every part of our lives."
