The Sanhedrin was the Supreme Court for the Land of Israel the highest Jewish judicial tribunal. Today, its counterpart in formation, met in the Old City of Jerusalem. They planned their future basing all matters on the Torah. Themes explored by the Sanhedrin will be the lost Jewish tribes from other parts of the world, restoring the Davidic monarchy, and (starting) the long road towards its chief goal of restoring the crown of Torah to its former glory.IOW, they are making preparations for Christ's return.
In addition to the establishment of the Sanhedrin, according to New Testament End Time prophecies, there will be a temple constructed in Jerusalem.
They have to believe in the Christ for His return don’t they?
