Day 3 Read: Acts 2:1-4
When the day of Pentecost arrived, they were all together in one place. 2 And suddenly there came from heaven a sound like a mighty rushing wind, and it filled the entire house where they were sitting. 3 And divided tongues as of fire appeared to them and rested on each one of them. 4 And they were all filled with the Holy Spirit and began to speak in other tongues as the Spirit gave them utterance.
Reflect: How does the arrival of the Holy Spirit fulfill the promise Jesus made in Matthew 28:20?
Consider: Pentecost was the second of the three great harvest festivals of Judaism, coming between Passover and Tabernacles. In the New Testament (cf. 1 Cor 16:8) it is referred to as “Pentecost,” which means fiftieth in Greek. In the Old Testament it is referred to as the Festival of Weeks or of the Firstfruits, the first term referring to its coming a “week of weeks” after Passover, the second to the fact that an offering of two loaves prepared from the wheat harvest was made on this day.
Respond: If you had been present, how do you think you would have responded to the sudden arrival of the Holy Spirit? How does the Holy Spirit reveal His presence in your life? How does having the Holy Spirit’s power make a difference in how you serve God?
