unless you believe in universalism...
people from every kindred tongue and nation are already and have been worshipping the Lord from Calvary on, and even the faithful strangers within the commonwealth of israel worshipped God.
certainly, the Gospel started for the Jew first, then to the Greek (gentile) at Pentecost.
it's amazing to me how we might either forget that Great Day too readily...or assume it has a Latter Rain gap thing waiting to happen (supposedly happening now)
it already happened.
Acts 2
1When the day of Pentecost arrived, they were all together in one place. 2And suddenly there came from heaven a sound like a mighty rushing wind, and it filled the entire house where they were sitting. 3And divided tongues as of fire appeared to them and resteda on each one of them. 4And they were all filled with the Holy Spirit and began to speak in other tongues as the Spirit gave them utterance.

Now there were dwelling in Jerusalem Jews, devout men from every nation under heaven. 6And at this sound the multitude came together, and they were bewildered, because each one was hearing them speak in his own language. 7And they were amazed and astonished, saying, “Are not all these who are speaking Galileans? 8And how is it that we hear, each of us in his own native language? 9Parthians and Medes and Elamites and residents of Mesopotamia, Judea and Cappadocia, Pontus and Asia, 10Phrygia and Pamphylia, Egypt and the parts of Libya belonging to Cyrene, and visitors from Rome, 11both Jews and proselytes, Cretans and Arabians—
we hear them telling in our own tongues the mighty works of God.” 12And all were amazed and perplexed, saying to one another, “What does this mean?” 13But others mocking said, “They are filled with new wine.”
so already jews who spoke the languages of 'every nation under heaven' received the Good News...it wouldn't be long before the Stone became a great mountain.
so we can easily say the nations worship the Lord right now.
and we know redeemed in heaven are from every nation.
i don't see anything not going according to Plan (A)
