If God has knowledge of an action which will be performed by someone, and it has been written on the Tablet of Fate, is it possible to resist it?
The foreknowledge of a thing is not the cause of its realization; for the essential knowledge of God surrounds, in the same way, the realities of things, before as well as after their existence, and it does not become the cause of their existence. It is a perfection of God. But that which was prophesied by the inspiration of God through the tongues of the Prophets, concerning the appearance of the Promised One of the Bible, was not the cause of the manifestation of Christ.
The hidden secrets of the future were revealed to the Prophets, and They thus became acquainted with the future events which They announced. This knowledge and these prophecies were not the cause of the occurrences. For example, tonight everyone knows that after seven hours the sun will rise, but this general foreknowledge does not cause the rising and appearance of the sun.
Therefore, the knowledge of God in the realm of contingency does not produce the forms of the things. On the contrary, it is purified from the past, present and future. It is identical with the reality of the things; it is not the cause of their occurrence.
In the same way, the record and the mention of a thing in the Book does not become the cause of its existence. The Prophets, through the divine inspiration, knew what would come to pass. For instance, through the divine inspiration They knew that Christ would be martyred, and They announced it. Now, was Their knowledge and information the cause of the martyrdom of Christ? No; this knowledge is a perfection of the Prophets and did not cause the martyrdom.
The mathematicians by astronomical calculations know that at a certain time an eclipse of the moon or the sun will occur. Surely this discovery does not cause the eclipse to take place. This is, of course, only an analogy and not an exact image.
