It is common knowledge that the Creator did not complete creation when He created it. And we can see in every corner of reality, in the general and in the particular, that it abides by laws of gradual development – from absence through the completion of its growth. For that reason, when the fruit tastes bitter in the beginning of its growth, it is not considered to be a flaw in the fruit, because we all know that the fruit has not yet finished its development.
And so it is in every aspect of reality, when some item appears bad and harmful to us, it is but a self-testimony of that item; that it is still in that transition phase – in the process of its development. Therefore, we cannot decide that it is bad and it is not wise for us to cast a flaw in it.
