There are several gifts of the Spirit which Christians have, thanks to the Holy Spirit. However, one does not "possess" ALL the gifts of the Spirit. Each Christian is gifted with ANY combination of the gifts, and we are even told to SEEK the "higher" ones, too!
So, the gift of prophecy is merely ONE of many gifts, and not ALL Christians have it. And the gift of prophecy is NOT what you seem to view it as, some sort of mystical fortune telling. Prophecy entails SPIRITUAL and Biblical prophecy, things related to God. It has nothing to do with lottery tickets, who will win the Triple Crown, or if you are going to meet a "tall, dark, and handsome man" tomorrow.
As for me and my household, we will serve the Lord.
MARANATHA! Come, Lord Jesus, COME!
