When Jesus cleansed the Temple, it wasn’t out of anger, but out of his zeal for the purity of God’s sanctuary. He was consumed and eaten up with this zeal, so much to that he would die as the true Temple and through his resurrection, build an expansive temple that includes all believers. And now, that same zeal for the old earthly Temple is still a part of Christ and he is purifying us as well in his zeal and giving us the same zeal for the Temple and Body of Christ.
