This passage is about the Pentecost, the coming of the Holy Spirit. The Lord commanded the Jews to observe it in order to give thanks for the first fruits of their harvest, which pointed to the fuller harvest to come. Now the "first fruits" of the completed spiritual harvest are being brought in with the outpouring of the Holy Spirit. Pentecost is for the church of Christ what the pay check is for the laborer, the financial profits are for the businessman, and the harvest is for the farmer. The Holy Spirit was poured out into the church.
“They were all filled by the Holy Spirit and began to speak in other tongues as the spirit gave them utterance” Acts 2:4. The ability to proclaim the mighty works of God in different languages was a supernatural gift. This work of the Spirit pointed to the spread of the gospel throughout the earth, with each nation hearing the gospel in their native language. It also means that all who believe will be united in their belief in Christ and will glorify God.
If you are a follower of Jesus Christ and have trusted that He is your Lord and Saviour, then the exact same Spirit mentioned in Acts 2 is living inside you right now. The Holy Spirit is dwelling in you. Acts 1:8 said, “You will receive power when the Holy Spirit comes upon you, and you will be my witnesses,” which is why as soon as the Spirit comes down among all these people, they begin witnessing, speaking, and declaring the wonders of God with their mouths because they’re empowered by the Holy Spirit. We see throughout the scriptures what the Holy Spirit does in our lives, through our lives, and for our lives. As a result, we must keep in mind that the primary purpose of the Spirit in our lives is for us to be witnesses.
The same Peter who denied Jesus three times, stood up and was proclaiming the gospel to thousands of people. What happened to Peter? The Holy Spirit happened to Peter. The Holy Spirit came upon him and totally changed him. So, I would like to encourage you today to witness to somebody around you, through your words and actions. Ask the same Holy Spirit to give you the opportunity to reach out to someone where you can include, invest and invite.
