But in the Lord's work, of all things, it should constantly be our aim to do the very best we are capable of. This attitude is content with a relatively low level of quality. With this attitude, we offer work and service to the Lord that are inferior even by human standards.
Mediocrity is to human endeavor what entropy is to physical systems.
It increases when things are left to themselves and no energy is introduced from outside the system. Rather than a contentment with mediocrity, we should have a commitment to excellence in whatever we do. It makes a big difference how high our goals are in the work we do.
