Joel 2:29

and also upon the servants and upon the handmaids, upon the lowliest of the land, in those days will I pour out My Spirit, all social distinction being abandoned in the New Testament era as far as the work of the Church is concerned. This prophecy was fulfilled, so far as its beginning is concerned, on the great Day of Pentecost, as Peter also states in the introduction to his powerful sermon held before the astonished inhabitants of the city of Jerusalem, Acts 2:17. But this event by no means exhausted its wonderful promises; for the Spirit of the Lord is being poured out on the members of the Church of the New Testament today and will continue to be given to all true believers until the end of time. But this great and wonderful deed of the Lord is placed side by side with His judgment upon the nations.
