The disciples, after being filled with the Holy Spirit, on the Day of Pentecost, began to speak in other tongues (different languages), as the Spirit was giving them the ability to speak out clearly and appropriately about the mighty works of God.

⁵ Now there were Jews living in Jerusalem, devout and God-fearing men from every nation under heaven. ⁶ And when this sound was heard, a crowd gathered, and they were bewildered because each one was hearing those in the upper room speaking in his own language or dialect. ⁷ They were completely astonished, saying, “Look! Are not all of these who are speaking Galileans? ⁸ Then how is it that each of us hears in our own language or native dialect? 

⁹ [Among us there are] Parthians, Medes and Elamites, and people of Mesopotamia, Judea and Cappadocia, Pontus and ^[a]Asia [Minor], ¹⁰ Phrygia and Pamphylia, Egypt and the districts of Libya around Cyrene, and the visitors from Rome, both Jews and proselytes (Gentile converts to Judaism), ¹¹ Cretans and Arabs—we all hear them speaking in our [native] tongues about the mighty works of God!”

Indeed, the Holy Spirit is the only One with the power to reach men and women of different nationalities, race and culture.

Today, before you go out into your sphere of influence, ask the help of the Holy Spirit to cross the boundaries of race, religion, culture with your Christlikeness. You are His ambassador.
