With and In
it is that during the days of his humiliation, the Spirit of Christ was on Christ, and therefore, and in this sense, ‘with’ the disciples. But at the exaltation, Christ would breathe his Spirit on his disciples. He would now indwell them in his identity as the Spirit of the exalted Saviour. He who was ‘with’ them in Christ’s presence would then be ‘in’ them as the Spirit of the incarnate and exalted Christ.
