Is the baptism with the Holy Spirit something that all Christians receive unconsciously at conversion?

"It is clear that the baptism with the Holy Spirit is always something clear and unmistakable, something which can be recognized by the person to whom it happens and by others who look on at this person. This is obviously a most vital and important principle. Those, of course, who tend to identify the baptism of the Holy Spirit with regeneration, and say that all who become Christians receive the baptism of the Holy Spirit on conversion naturally minimize this, as they must do, of necessity. Regeneration is something unconscious, not experimental; and the great point is that it is a mysterious, miraculous act worked in the depths and the vitals of the soul, and no man can tell you the moment when he was regenerated. Everybody is agreed about that - that regeneration is non-experimental. You later begin to discover the fact that you have been made regenerate and give evidence of it.

"But now here we are dealing with something which is very different. The very essence of this is that it is conscious, that it is experimental, obvious, plain, and clear; not only to the recipient but also to those who are familiar with him...I think the bible makes it perfectly clear, it makes it quite beyond any doubt, that this is something essentially experimental, which involves a mystical experience, to use such a term."

Is this infilling with the Holy Spirit repeatable and what is the evidence?

"This is ultimately a biblical question: what is the teaching of the Scripture? We read in Acts 4:8: 'Then Peter, filled with the Holy Ghost' - remember he had been filled on the day of Pentecost but here he is now with John standing before the court, the authorities, and, because he is in a predicament he is given another filling - 'Peter, filled with the Holy Ghost, said unto them...'

"But still more striking, of course, is what you find in 4:31: 'And when they had prayed, the place was shaken where they were assembled together; and they were all filled with the Holy Ghost, and they spake the word of God with boldness...With great power gave the apostles witness of the resurrection of the Lord Jesus: and great grace was upon them all.

"Restrained! Quiet! Unobtrusive! My dear friends, why not listen to the evidence? This is the kind of thing that happens when the Spirit 'comes' upon man, even the building was shaken, and this tremendous uplifting took place in the experiences of the apostles and the other believers."
