Have you ever heard a preacher speak and have thought or said “They are on fire today”? Could it be the Holy Spirit is using that person to speak to you just as the disciples spoke in Acts 2?
When the day of Pentecost arrived, they were all together in one place. And suddenly there came from heaven a sound like a mighty rushing wind, and it filled the entire house where they were sitting. And divided tongues as of fire appeared to them and rested on each one of them. And 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. And at this sound the multitude came together, and they were bewildered, because each one was hearing them speak in his own language. And they were amazed and astonished, saying, “Are not all these who are speaking Galileans? And how is it that we hear, each of us in his own native language? Parthians and Medes and Elamites and residents of Mesopotamia, Judea and Cappadocia, Pontus and Asia, Phrygia and Pamphylia, Egypt and the parts of Libya belonging to Cyrene, and visitors from Rome, both Jews and proselytes, Cretans and Arabians—we hear them telling in our own tongues the mighty works of God.” And all were amazed and perplexed, saying to one another, “What does this mean?” But others mocking said, “They are filled with new wine.”
-Acts 2:1-13 (ESV)
The disciples weren’t literally on fire, but Luke says “as of fire”. Fire in the Bible, specifically the Old Testament, often referred to God’s presence, His holiness and purity. Fire was also used to burn impurities, thus purifying. So when we think “they are on fire”, there is a good possibility that God’s presence is purifying an impurity in our lives.
In addition, God used the Holy Spirit, speaking through His disciples, to share the Good News of Jesus Christ with people from different regions, cultures, and languages (Acts 2:9-11). Though we may not be speaking in ‘tongues’, the Holy Spirit uses us to speak in ways that many different types of people can know the love of Jesus Christ.
