In Acts 2:17 – 21, Peter quotes a prophecy of Joel found in Joel 2:28-32: “And it shall come to pass in the last days, saith God, I will pour out of my Spirit upon all flesh: and your sons and your daughters shall prophesy, and your young men shall see visions, and your old men shall dream dreams: And on my servants and on my handmaidens I will pour out in those days of my Spirit; and they shall prophesy: And I will shew wonders in heaven above, and signs in the earth beneath; blood, and fire, and vapour of smoke: The sun shall be turned into darkness, and the moon into blood, before the great and notable day of the Lord come: And it shall come to pass, that whosoever shall call on the name of the Lord shall be saved.”
John Piper, in a sermon entitled “I Will Pour Out My Spirit” – https://www.desiringgod.org/messages/i-will-pour-out-my-spirit states:
“…Joel’s prophecy, that Peter quotes in Acts 2:17–21, makes clear that the last days will be mixed days—days of powerful witness (vv. 17–18) and days of terrible calamity (vv. 19–20). When Joel looked into the future, God didn’t tell him how many years would separate the different parts of the last days that he was describing. He saw the last days as all one piece. Some of what he saw was nearer to the beginning of the last days, and some was nearer to the end of the last days.
The Bright Part of Joel’s Prophecy
So when you read his prophecy, it has two parts—a bright part and a dark part. The bright part is verses 17–18,
I will pour out my Spirit upon all flesh, and your sons and your daughters shall prophesy, and your young men shall see visions, and your old men shall dream dreams; yea, and on my menservants and my maidservants in those days I will pour out my Spirit; and they shall prophesy.
In other words Joel says that one feature of the last days will be the outpouring of the Holy Spirit on people of every kind—men and women, young and old, high and low. God’s people will be clothed with power; they will receive power. And the main effect of this power seems to be bold, prophetic speech. Believers of all kinds are going to be so gripped by the Spirit of God that they see the greatness of Jesus and the purpose of Jesus with extraordinary clarity and speak it with extraordinary boldness. That’s the bright part of Joel’s prophecy.
The Dark Part of Joel’s Prophecy
The dark part is in verses 19–20,
And I will show wonders in the heaven above and signs on the earth beneath, blood, and fire, and vapor of smoke; and the sun shall be turned into darkness and the moon into blood, before the day of the Lord comes, the great and manifest day.
In other words there will be natural catastrophes; there will be war and bloodshed; there will be conflagration and devastation.
The Answer to the Second Question
So, what is the answer to our question? If war broke out tomorrow in the Middle East with terrible bloodshed and earthshaking ferocity, and began to draw the whole world into conflict, would that be a sign that God’s purpose for our day is not a great spiritual awakening but only a bleak downward spiral of calamity and moral collapse till the end?
No. On the contrary, there is a promise that in the last days the Spirit will be poured out on all flesh—all the nations will be reached. The true church of Christ will be awakened and revived and sent with extraordinary passion and zeal and prophetic power, and—right in the midst of terrorism and war and persecution and natural disasters—the flaming end-time church of Christ will finish the Great Commission, and welcome the King…”
So yes, we believe that there are Prophets today.
