But Peter, taking his stand with the eleven, raised his voice and declared to them: “Men of Judea and all you who live in Jerusalem, let this be known to you and give heed to my words. For these men are not drunk, as you suppose, for it is only the third hour of the day; but this is what was spoken of through the prophet Joel: ‘And it shall be in the last days,’ God says, ‘That I will pour forth of My Spirit on all mankind; 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 bondslaves, both men and women, I will in those days pour forth of My Spirit And they shall prophesy. ‘And I will grant wonders in the sky above And signs on the earth below, Blood, and fire, and vapor of smoke. ‘The sun will be turned into darkness And the moon into blood, Before the great and glorious day of the Lord shall come. ‘And it shall be that everyone who calls on the name of the Lord will be saved.’ Acts 2:14–21, NASB
Thus began the Apostle Peter’s sermon following the outpouring of the Holy Spirit on the Day of Pentecost just 10 days following our Lord’s Ascension. I am going to walk through this sermon with you so that we can see how the Gospel works when preached with power and with the right focus. Who is being glorified in vv. 14–21 above? Is it the preacher Peter? Is it those prophesying? Is it those responding? No, it is God who is causing this to happen through the moving of His mighty hand. What will be the result as Peter summarizes in v. 21? Everyone who calls upon the name of the Lord shall be saved. Here is that verse from Greek, “και εσται πας ος εαν επικαλεσηται το ονομα κυριου σωθησεται.” The NASB’s rendering of “calls on” translates επικαλεσηται the aorist, subjunctive, middle form of ἐπικαλέομαι or epikaleomai, which, in this context, is making use of the name of the Lord in adoration as Lord and Saviour. This is a turning to Him for salvation from the hour of judgment and wrath to come. That is how Peter opens his sermon. Let us see the rest.
