I found this on the sacredcharge.com website. They have some really awesome resources for people going after a lifestyle of prayer and fasting - you should check it out! : )
"Beware of any work for God which enables you to evade concentration on Him. A great many Christian workers worship their work. The one concern of a worker should be concentration on God, and this will mean that all the other margins of life, mental, moral and spiritual, are free with the freedom of a child, a worshipping child, not a wayward child.
…. There is no responsibility on you for the work; the only responsibility you have is to keep in living constant touch with God, and to see that you allow nothing to hinder your cooperation with Him. The freedom after sanctification is the freedom of a child, the things that used to keep the life pinned down are gone. But be careful to remember that you are freed for one thing only- to be absolutely devoted to your co-Worker.
…. God engineers everything; wherever He puts us our one great aim is to pour out a whole-hearted devotion to Him in that particular work.
