But Peter, standing with the eleven, lifted up his voice and addressed them: “Men of Judea and all who dwell in Jerusalem, let this be known to you, and give ear to my words. For these people are not drunk, as you suppose, since it is only the third hour of the day. But this is what was uttered through the prophet Joel
“‘And in the last days it shall be, God declares,
that I will pour out my Spirit on all flesh,
and your sons and your daughters shall prophesy,
and your young men shall see visions,
and your old men shall dream dreams;
even on my male servants and female servants
in those days I will pour out my Spirit, and they shall prophesy.
And I will show wonders in the heavens above
and signs on the earth below,
blood, and fire, and vapor of smoke;
the sun shall be turned to darkness
and the moon to blood,
before the day of the Lord comes, the great and magnificent day.
And it shall come to pass that everyone who calls upon the name of the Lord shall be saved.’Acts 2:14-21 (ESV)
In Acts 2, Peter is filled and empowered by the Holy Spirit as he preaches directly from the Scriptures about Christ. In the same way in our current time, the Spirit of God empowers preachers and teachers to proclaim the Gospel, creating a worshipping, redeemed people that are changed by the Word.
