We all know that in the New Testament, it is recorded that at the day of the Pentecost, the Holy Spirit descended on the hoi polloi like wind and people started speaking in tongues. Pentecost as an idiom means a spiritual awakening.
Example: When the Pentecost happened to me, I became Spirit filled.
Let the Pentecost happen to all people of all nations.
Pentecost is an experience of happiness and peace.
