There were rumors that Christ had come. Well, quite honestly, I think these guys were smart enough to realize that no one would buy that tale unless they were seeing the physical body of Christ and graves popping open. Christ knew exactly what the Pharisees were asking. I go to prepare a place for you. First, Judas knew that Christ said the kingdom would not be obvious but that His people would know it.
Christ response is crucial.
He was telling Judas that those in whom He would come to dwell were the mansions in the Father's house. Ye also, as lively stones, are being built up a spiritual house, an holy priesthood, to offer up spiritual sacrifices, acceptable to God by Jesus Christ. The place was the house or Temple of God that was being built. That house consisted of many dwelling places. At the parousia, Christ came to indwell that house.
