There is fixed time and and a earlier time to bring Meshiach. Is the argument if we merit it before the fixed time what will happen? Obviously if we merit it, we bring Meshiach spontaneously. Maybe we generate the merit by working for his coming, צפית לישועה?, so he will come earlier. The Minchas Elozor’s view will be that we cannot generate the merit by our actions because we would violate the three shavuos, so only elimination of futile hatred can accelerate his coming. When the fixed time arrives, if we don’t merited, a melech kasha kehaman, a harsh king like Haman will bring us back to teshuva and Meshiach will come spontaneously, in either case whether we merited or not.
