Then the greater the vision, the greater the display of the power of the enemy. So when individuals are blessed with visions, revelations, and great manifestations, look out, then the Devil is nigh you, and you will be tempted in proportion to the visions, revelation, or manifestation you have received.
God never bestows upon his people, or upon an individual, superior blessings without a severe trial to prove them, to prove that individual, or that people, to see whether they will keep their covenants with him, and keep in remembrance what he has shown them.
Be thankful every morning when you get up that you have something to do that day, which must be done, whether you like it or not.
As to the questions asked—even by faithful Saints—such as, "If what is going to happen is 'all set,' why pray?," the answer is that God foresees, but He does not compromise our agency. All the outcomes are not, for our purposes, "all set." True, God's foreseeing includes our prayers, our fasting, our faith, and the results that will thereby be achieved. But until our mortal actions occur and our decisions are made, things are not "all set." The Father foresaw the Atonement, but the Atonement was not wrought until the very moment of Christ's death when He gave up His spirit, which He had the power to retain.
The time will come when we will thank Him for saying no to us with regard to some of our petitions. Happily, God in His omniscience can distinguish between our surface needs (over which we often pray most fervently) and our deep and eternal needs. He can distinguish what we ask for today and place it in relationship to what we need for all eternity. He will bless us, according to our everlasting good, if we are righteous.
