“I do not believe in the God of theology who rewards good and punishes evil. My God created laws that take care of that. His universe is not ruled by wishful thinking, but by immutable laws.”

Variant: A world contrary to God must be kept within bounds by the world’s sword. But true Christians love God and their neighbors as themselves; they commit no evil by the grace of God. It is not necessary to compel them to goodness since they know better what is good than the law imposing authority.

Ich glaube an Spinozas Gott, der sich in der gesetzlichen Harmonie des Seienden offenbart, nicht an einen Gott, der sich mit Schicksalen und Handlungen der Menschen abgibt.
24 April 1929 in response to the telegrammed question of New York's Rabbi Herbert S. Goldstein: "Do you believe in God? Stop. Answer paid 50 words." Einstein replied in only 27 (German) words.

Similarly, in a letter to Maurice Solovine, he wrote: "I can understand your aversion to the use of the term 'religion' to describe an emotional and psychological attitude which shows itself most clearly in Spinoza... I have not found a better expression than 'religious' for the trust in the rational nature of reality that is, at least to a certain extent, accessible to human reason."

Albert Einstein, in response to the telegrammed question of New York's Rabbi Herbert S. Goldstein in (24 April 1929) ; he later expanded on his comments about Spinoza's and his own ideas on religion elsewhere : "I can understand your aversion to the use of the term "religion" to describe an emotional and psychological attitude which shows itself most clearly in Spinoza … I have not found a better expression than "religious" for the trust in the rational nature of reality that is, at least to a certain extent, accessible to human reason." — as quoted in Einstein : Science and Religion by Arnold V.

The Nature, Importance and Liberties of Belief (1873)
Context: Now, evidence to a man is that which convinces his mind. It varies with different men. An argument to a man who cannot reason is no evidence. Facts are no evidence to a man who cannot perceive them. A sentimental appeal is evidence to a man whose very nature moves by emotion, though it may not be to his neighbor.
So then, when men come to the investigation of truth, they are responsible, first, for research, for honesty therein, for being diligent, and for attempting to cleanse their minds from all bias of selfishness and pride. They are responsible for sincerity and faithfulness in the investigation of truth. And when they go beyond that to the use of their faculties, the combination of those faculties will determine very largely, not, perhaps, the generic nature of truth, but specific developments of it. And as long as the world stands there will be men who will hold that God is a God of infinite love and sympathy and. goodness with a residunm of justice; and there will be men who will believe that God is a God of justice with a residunm of love and sympathy and goodness; and each will follow the law of his own mind. As a magnet, drawn through a vessel containing sand and particles of iron, attracts the particles of iron but does not attract the sand; so the faculties of a man's mind appropriate certain facts and reject others. What is evidence to a man will depend upon those of his faculties whk at work upon the things which are presented as evidence.
