Here are three significant prophecies of the outpouring of the Holy Spirit in the end times. Two have to do with revival, one with judgment.
Zechariah 12:10 I will pour out on the house of David and the inhabitants of Jerusalem the spirit of grace and supplication and they will look upon Me whom they have pierced…
In this astounding Messianic prophecy, the same One who says “I” will pour out the spirit, also says, they will look upon “Me.” The One who pours out the Spirit is the same as the One who was pierced.
This prophecy refers to a spirit of revelation that will give the people of Israel understanding that the One we pierced (crucified) is indeed the divine savior, Yeshua the Messiah.
The second is similar but more global.
Acts 2:17-18 And it shall come to pass in the last days that I will pour out My Spirit on all flesh… I will pour out My Spirit.
Peter quotes the prophet Joel, as he explains the baptism of the Holy Spirit and fire on Pentecost morning. He seems to be indicating that there will be a similar outpouring of the Holy Spirit in the end times, yet much wider in scope.
The outpouring in Jerusalem described by Zechariah is part of the promise that “All Israel will be saved” – Romans 11:26. The people of Israel receive revelation about Yeshua, resulting in a sweep of salvation across the nation. The revival in Israel is connected to the world-wide revival. “I will pour out My spirit on all flesh…” is parallel to “I will pour out on the house of David…”
At the end of the end times, seven angels are instructed to pour out seven golden bowls of punishment from God.
Revelation 16:1 Go pour out upon the earth the seven bowls of the wrath of God.
These bowls of wrath are actually evidence of the grace of God, as it is the last warning before the judgment of the Lake of Fire. The bowls of wrath are extreme measures in a last effort to save those who are headed toward eternal punishment.
The same Holy Spirit empowers the saints, draws sinners to repentance, and brings judgment upon the wicked. Tribulation and revival occur simultaneously. Both the compassion of God and His holiness are openly displayed to the world.
