You may be missing the point of Pentecost and why Jesus as He was going to the Father after walking around for forty days after the Resurrection, told His mother and the disciples to wait until the Holy Spirit comes to “teach you all things” ...
... and Mary waited with the Disciples in the upper room, prob the same room where Jesus had the Last Supper/or Passover Meal the night before He was crucified.
Then the Holy Spirit fell... and later Peter stood up to say that ‘this is that’ of which the Prophet Joel spoke: I shall pour out My Spirit on all flesh... etc.

We’ve been in the Last Days, ever since Jesus ascended unto the Father, and sent the Holy Spirit to the church. There is no other re-division of time, other than the last 7 years told of in the Book of Revelation.
In our church we have adopted a church of refugees from Africa. It started off with just Rwandan refugees. It now has something like people for 10 nations from Africa.
The leaders of the church are from tribes that still fight against each other. It is an amazing testimony of the reconciliation of God when two close brothers in Christ talk about how their tribes and relatives killed the other’s families.
On Pentecost their church combined with our church (which they do once a month) and it was an amazing service of just music. (We do that once a year).
Songs in English, Swahili, and Spanish. We have adopted a Chinese church and I’m guessing in the next year or so we will add a song in Chinese.
I’m still a fairly bigoted guy. Yes - I notice a person’s race. But God is making progress with me!
