Matthew mead on indwelling of the Holy Spirit in both testaments.

“The great blessing of the Spirit, how sparingly was that given out at first, to a very few in number, and that in a small measure, in so much that it is said comparatively, the Spirit was not given. It was not given, that is, in comparison of what was to be when Christ had ascended. For the fullest enjoyment of the extraordinary gifts, and saving graces of the Spirit was reserved until Christ’s ascension, such as the fruit of his exaltation and triumph. So that the Spirit is said to be, “poured out,” in that day; (Joel 2:28). Therefore there is a greater measure of the Spirit enjoyed under the Gospel than ever was before, and let me tell you there is yet behind, another pouring out of the Spirit promised, that shall be greater than any ever yet was.”
