God originally created the earth with such perfection and beauty that the angels shouted with joy! Our Creator does all things in an organized manner and completes all His works in exquisite splendor. But the earth had somehow become formless and chaotic so that God had to refashion it before man could be created.

Basic Doctrines: Satan's Origin and Destiny
God continuously, from the beginning of the Book on, reveals Himself working through one man at a time. Does God send two or three or five ambassadors speaking somewhat different things to the same country at the same time? That would be confusion, and "God is not the author of confusion" (I Corinthians 14:33). He avoids confusion by speaking through one voice, and we need to understand that. We need to believe it and make it a part of the operation of our lives. When we become confused about the voice God is speaking through, the church tends to blow apart, and people go their own way.
To restore the holiness of His name and to guarantee that we enter into His Kingdom, God leads us into groups where we can continue to be sustained until we learn this bitter but very vital lesson and submit to Him by following the voice that He sent into this world to restore and preach the doctrine to which He wants us to conform. He does this so that we will be transformed into the image that He wants by our making right and holy choices.
What kind of leadership would it show God to have if He spoke in a confused tongue, as it were, having two or more men in the same area saying different things about the path to the Kingdom of God? Doctrine is that recipe that will form the correct product in the end—if it is believed and applied in our lives through the choices we make.
