The only ones among you who will be really happy are those who will have sought and found how to serve. (Albert Schweitzer, 19th-20th century Alsatian humanitarian)
That was the one thing Schweitzer said he knew about others whose destiny he didn’t know. He had given his life in a variety of ways, including giving benefit concerts in Europe to raise funds for his medical work in Africa. Awarded the Nobel Peace Prize in 1952, he was recognized as a true servant to all whom he could help. Certainly, a worthy example to follow.
God has given each of you a gift from his great variety of spiritual gifts. Use them well to serve one another. (1 Peter 4:10)
