Without it, God's people cannot live on the edge of revelation nor know what the Father's will is for them. Second-guessing is just not an acceptable way of running a ministry for God's servants must always know what to do and, when necessary, be warned beforehand of what is going to occur. The gift of prophecy is not, however, a right. It is Yahweh who chooses, or does not choose, to reveal the future. We cannot demand to know.
All true prophecy comes uninvited and unexpected.
Though we should always be prepared to receive prophecy we have no business demanding God tell us what is to happen. It has received prophecies about indivuals and about nations. We have witnessed such prophecies fulfilled time and time again so as to leave us in no doubt that this is a genuine gift of the Spirit. Some still await future fulfilment. You will read on this site some amazing modern prophecies that were fulfilled to the letter.
