Ezekiel 1:19 & 20
"When the living creatures moved, the wheels beside them moved; and when the living creatures rose from the ground, the wheels also rose. Wherever the spirit would go, they would go, and the wheels would rise along with them, because the spirit of the living creatures was in the wheels." NIV translation
The creatures were in tune with God and controlled the wheels. They had a spirit of complete obedience to God and that spirit was also in the wheels. The wheels knew their purpose, remained focused on that, and simply obeyed. We can learn much for our walk with the Lord from these wheels. God has given each of us a purpose and His presence will be there with us in the form of the Spirit. If we remain focused on our purpose and tuned in to the Spirit, He can and will work through us for His glory.
