" Have you realized what it means that God sent the Holy Spirit into our hearts? It is nothing less than this: Christ, who had been with the disciples on earth but not in them, came back to them in the Spirit, now to dwell in them just as He had before dwelt with them. All that we read of the wondrous change that came over the disciples—their selfishness changed into love, their pride into humility, their fear of suffering into boldness and joy, their unbelief into fullness of faith, their feebleness into power—was owing to this one thing: the glorified Christ had come to dwell within them as their Life. "
