The risk of a wrong decision is preferable to the terror of indecision. - Moshe ben Maimon

According to each one of the different theories there are things which are impossible, whose existence cannot be admitted, and whose creation is excluded from the power of God, and the assumption that God does not change their nature does not imply weakness in God, or a limit to his power. Consequently things impossible remain impossible, and do not depend on the action of an agent. It is now clear that a difference of opinion exists only as to the question to which of the two classes anything belongs; whether to the class of the impossible, or to that of the possible. Note it.

Scripture says:—If a man should rise, pretend to be a prophet, and show you his signs by which he desired to convince you that his words are true, know that God intends thereby to prove to the nations how firmly you believe in the truth of God's Word, and how well you have comprehended the true Essence of God; that you cannot be misled by any tempter to corrupt your faith in God. Your religion will then afford a guidance to all who seek the truth, and of all religions man will choose that which is so firmly established that it is not shaken by the performance of a miracle. For a miracle cannot prove that which is impossible; it is useful only as a confirmation of that which is possible, as we have explained in our Mishneh-torah.

It is man's duty to love and to fear God, even without hope of reward or fear of punishment.
