To use an easier metaphor, say you are challenged to a game of chess by a friend. You may choose to decline their offer, or you may choose to accept it - that is voluntary. However, say you choose to accept their challenge and then you subsequently defeat your opponent. By "choosing" to play the game, did you therefore "choose" to win the game? No. The winning was the outcome of the operation of the game itself. You can choose how you play, but ultimately no matter how you play no single voluntary decision "to win" factors into the outcome of the game. The outcome of the game represents the conclusion of the process, not a conscious, voluntary determination of either of the players. Just as a belief (a position which you hold to be true) is the conclusion of the intellectual process of investigation or assessment. You may choose the method, but you cannot choose the outcome.
