Every act which is against religious belief is regarded as a sin, because it is against God. On the other hand, every act which agrees with religious belief is not regarded as a sin, because it has God's approval. Since polygamy was part of the religious belief of the Children of Israel, and the same is true of the Mohammedans today. it could not, nor can it now, be counted against them as a sin. Moreover, it is to prevent it being a sin for them that they remain natural people, and they do not become spiritual.

The natural man is unable to see that there is anything sinful in matters which have the approval of the accepted religion; only a spiritual man can see this. It is for this reason that, although the Koran tells them to acknowledge our Lord as the Son of God, they still do not approach Him, but rather Mohammed. This too is why they remain natural so long, and so do not know that polygamy contains any evil, not even any wantonness. The Lord also says:

If you were blind, you would have no sin; but now you say that you see, so your sin remains (John 9:41).

Since polygamy cannot be held to convict them of sinning, they have their own heavens after death (342), and there they experience such joys as their manner of life allows.
