(sorry - I worked 12 hours yesterday)
Do not be wise in your own eyes, Fear the Lord and turn away from evil.
At some point we all say that we are wise, we know what to do, when to do it and how to do it, and we have a tenancy to take our eyes off the Lord and take control of the reins ourselves. When eyes are off of God, it is easy to get caught up in the world and even do ungodly things. When we seek the Lord in our decision making, even for the little things in the day, then we are sure to not go wrong. Know that God wants us to consult him, to realize that if we don't keep Him in mind, we may just be making wrong decisions. We may not think we are doing what it is called evil, but if it is not pleasing to God, it might as well be evil.
