World renowned conductor Leonard Bernstein said that the second violin is the hardest instrument to play. It's because few people play the second violin with the same eagerness with which they played the first violin. Yet, without playing the second violin, it is not easy to make beautiful harmony. It is the same with various fields of our life. Just as a small nail is necessary in a building everyone has an important role in a group no matter how small the role he has. Only when we realize this fact, can we make beautiful harmony of our life.
"And the eye cannot say to the hand, 'I have no need of you'; or again the head to the feet, 'I have no need of you.'" (1 Corinthians 12:21)
