870. Since there is a practical reason why the future is hidden, why does God sometimes permit it to be revealed?
“Because in such cases this foreknowledge facilitates the accomplishment of what is to be, rather than hinder it, by making the persons to whom it is revealed act in a different manner than they would otherwise act. In addition, it is often a trial. The prospect of an event may awaken more or less honorable thoughts. For example, if individuals learn that they will receive an inheritance that they had not expected, they may be tempted by greed, by elation at the prospect of increasing their worldly pleasures, or by a desire for the death of their benefactor, so that they may obtain it sooner. On the other hand, this prospect may awaken good and generous thoughts in them. If the prediction is not fulfilled, it is a test of how they bear disappointment. They acquire the merit or reproach of the good or bad thoughts they have by their expectation of the event anticipated.”
