Though an outstanding singer's solo may be beautiful, the harmony of a choir leaves you with an impression that you can't feel from a solo. Likewise, if several people become one and unite their strength and wisdom, they can demonstrate great ability. It is like a cord that consists of three stands cannot be quickly unraveled (Ecclesiastes 4:12). Therefore, being united with others in respect and love is more important than sticking to your own opinion, thought and theory.
"Again I say to you, that if two of you agree on earth about anything that they may ask, it shall be done for them by My Father who is in heaven" (Matthew 18:19).
