Ladies and gentlemen , when it comes to the issue of getting married to the right man or woman God has made for you how important is it to follow the prophecies of your pastor?

For example, you have decided to say yes to someone you have been dating for years and you guys love each other but along the line a prophecy came forth that he/she is not your rightful partner. Is it advisable to follow your heart and go ahead with the marriage plans or just call off the relationship?
