There are many persons whom constant grants of His Bounties turn them wicked and fit for His punishment and there are many more who have become vain and self- deceptive because the Merciful Allah has not exposed their weaknesses and vices to the world and the people speak highly about them. All this is an opportunity. No trial of the Lord is more severe than the time He allows (in which either you may repent or get deeper into vices).
