Negate your own will in favor of God's will (Ethics of the Fathers 2:4).
If I surrender my will and turn my life over completely to the will of God, do I not thereby abrogate my power of free choice?
Certainly not. Take the example of a child who receives money for his birthday. An immature child may run off to the toy store or candy store and spend the money on everything his heart desires. He may indeed have several moments of merriment (although a stomach ache from indulging too heavily in confections is a possibility). Without doubt, however, after a short period of time those moments of enjoyment will be nothing but a memory, with the candy long since consumed and the broken toys lying on the junk heap.
A wiser child would give the money to a parent and ask that it be put into some type of savings account where it can increase in value and be available in the future for things of real importance.
Did the second child abrogate his prerogative of free choice by allowing the parent to decide how to invest the money? Of course not. In fact, this was a choice, and a wise choice as well as a free choice.
We can choose to follow our own whims or we can choose to adopt the will of an omniscient Father. We are wise when we make the second choice.
