"The Pentecostal Wind and Fire"
From the descent of the Holy Ghost at the beginning we may learn something concerning His operations at the present time. Remember at the outset that whatever the Holy Spirit was at the first, that He is now, for as God He remaineth forever. the same: whatsoever He then did he is able to do still, for His power is by no means diminished.
As saith the Prophet Micah, "O thou that art named the house of Jacob, is the spirit of the Lord straitened?"
We should greatly grieve the Holy Spirit if we supposed that His might was less today than in the beginning. Although we may not expect, and need not desire, the miracles which came with the gift of the Holy Spirit, so far as they were physical, yet we may both desire and expect that which was intended and symbolized by them, and we may reckon to see the like spiritual wonders performed among us this day.
