No matter how self sufficient you may consider yourself to be, no matter how well you know how to do something, you are limited by your isolation from the knowledge of God.
Human beings were created to walk together with God and to yield to His wisdom, understanding and knowledge. What we can do without Him is amazing but what we can do with Him is phenomenal.
The simplicity of productive and fulfilling living is found in ready obedience to His Word.
Whatever He says, Do it.
