When the Day of Pentecost had fully come, they were all with one accord in one place. And suddenly there came a sound from heaven, as of a rushing mighty wind, and it filled the whole house where they were sitting. Then there appeared to them divided tongues, as of fire, and one sat upon each of them. And they were all filled with the Holy Spirit and began to speak with other tongues, as the Spirit gave them utterance.
The promise is fulfilled and the church is empowered with the Holy Spirit.
The group did not relish and bask in the Holy Spirit. They hit the streets to proclaim God’s grace through Jesus.
This is what the Holy Spirit does for believers – empower us to tell of Good News of Christ.
If you aren’t doing that, then pray and seek God. Ask Him to fill you with the Holy Spirit for His glory.
