v 28. Then, after doing all those things,
I will pour out my Spirit upon all people.
The promise of the Holy Spirit.
This section starts with a call for action.
Blow the ram’s horn in Jerusalem! Announce a time of fasting; call the people together for a solemn meeting. Gather all the people— the elders, the children, and even the babies….. Let them pray, “Spare your people, Lord!
In these circumstances the call was not for social distancing, but for a coming together in unity. Joel sees God acting in response to the united prayers of His people. Verses 18-27 foresee the restoration of people and land to a harmonious state of plenty. It is a beautiful description of what God can do in response to the prayers of His people.
But Joel takes the matter even further, beyond the restoration of land and people, to a vision of God pouring out His Holy Spirit on all people. This is the section that is quoted by Peter in Acts 2 to explain what was happening on the Day of Pentecost.
It was this time of repentance, to be followed by the outpouring of the Holy Spirit, that form the prelude to chapter 3 and it’s marvellous prophecies.
