Read Acts 2:1-8

They were completely amazed. “How can this be?” they exclaimed. “These people are all from Galilee, and yet we hear them speaking in our own native languages!” Acts 2:7-8 (NLT)

The miracle of Pentecost – Jesus promised that the Holy Spirit would come, and he comes. The Holy Spirit enables people from all nations to hear from God what they need – who they are, who Jesus is, how they need him, and what he did for them – they need to hear the gospel. And it starts with the disciples resting, waiting on God. That enables God to use them mightily to draw many people to repentance.
