Our belief in God’s Omniscience is beautifully expressed in the Musaph prayer of New-year: “Thou rememberest the work of bygone times, and thinkest of all the imaginations of former days; all hidden things are revealed before thee; also all the multitude of hidden things which are from the beginning. For there is no forgetting before the throne of thy glory, and nothing is concealed from thine eye. Thou rememberest every deed, and no thought is hidden from thee. Everything is revealed and known before thee, O Lord our God, who beholdest and seest to the end of all generations.” Eleventh Principle.—“I firmly believe that the Creator, blessed be He, rewards those who keep His commandments, and punishes those who transgress His commandments.” The immediate reward and punishment for our conduct we receive in the pleasure and happiness we experience in doing something good, and in the grief and remorse we ought to feel on learning that we have displeased the Almighty by our conduct. As a rule, every good act leads to further good acts, and every sin to further sins; and our Sages say therefore: “The reward of a good act (‏מצוה‎) is another good act, and the punishment for a transgression is another transgression.” But when we speak of the principle of Retribution, we generally mean such reward and punishment as is given in addition to the feeling of happiness or unhappiness inseparable from our actions. This principle of retribution has been proclaimed in the grand Revelation made to all Israel on Mount Sinai, in the Decalogue which has been accepted by all civilised nations as the basis of religion: “I the Lord thy God am a jealous God, visiting the iniquity of the fathers upon the children, upon the third and upon the fourth generation of them that hate me; and showing mercy unto thousands of them that love me and keep my commandments” (Exod. xx. 5, 6). We understand the doctrine of retribution only in its general outlines; we are convinced of the truth of the Divine words, “There is no peace to the wicked” (Isa. lvii. 21); but how the law is applied in every single case is known to God alone. It is presumptuous on the part of short-sighted man to criticise God’s judgments, and to find injustice in the seeming prosperity of the wicked and the seeming misery of the righteous. What man is able to estimate the merits of his neighbour fully and correctly? “For the Lord seeth not as man seeth; for man looketh on the outward appearance, but the Lord looketh on the heart” (1 Sam. xvi. 7). This our inability of rightly estimating the merits of our neighbour’s actions, is illustrated by the Biblical narrative of Cain and Abel. Both brought sacrifices to the Lord; and we cannot discover any difference in their actions, and yet the sacrifice of Cain was rejected by God and that of Abel was accepted. Some important element there must therefore be in man’s deeds which is hidden from his neighbour’s eye, but is known to the Almighty.
