John 7:39

The Holy Ghost was not yet given] Under Christianity, the Holy Spirit, though personally distinct from Christ, is still the Spirit of Jesus, i.e. the Spirit of the Saviour. He could not, however, become this until the saving work of Christ was complete, until Christ had died for our sins upon the cross, risen again for our justification, and ascended into heaven to plead the merits of His sacrifice with the eternal Father. Hence the Comforter could not be given as the Comforter, until Jesus had been glorified: cp. John 16:7.
