God did not, as the Bible says, make man in His image; on the contrary man, as I have shown in The Essence of Christianity, made God in his image. - Ludwig Feuerbach

Religion is the dream of the human mind. But even in dreams we do not find ourselves in emptiness or in heaven, but on earth, in the realm of reality; we only see real things in the entrancing splendor of imagination and caprice, instead of in the simple daylight of reality and necessity.

Christianity set itself the goal of fulfilling man’s unattainable desires, but for that very reason ignored his attainable desires. By promising man eternal life, it deprived him of temporal life, by teaching him to trust in God’s help it took away his trust in his own powers; by giving him faith in a better life in heaven, it destroyed his faith in a better life on earth and his striving to attain such a life. Christianity gave man what his imagination desires, but for that very reason failed to give him what he really and truly desires.

Religion is indeed essential to or innate in man, but … this is not the religion of theology or theism, not an actual belief in God, but solely the religion that expresses nothing other than man’s feeling of finiteness and dependency on nature. … I distinguish religion from theism, the belief in a being distinct from nature and man. … Today theism, theology, the belief in God have become so identified with religion that to have no God, to theological being, is considered synonymous with having no religion. But here we deal with the original elements of religion. It is theism, theology, that has wrenched man out of his relationship with the world, isolated him, made him into an arrogant self-centered being who exalts himself above nature. And it is only on this level that religion becomes identified with theology, with the belief in a being outside and above nature as the true God. Originally religion expressed nothing other than man’s feeling that he is an inseparable part of nature or the world.
