From this chapter (Rev. Rev. 7:1+) it should be evident that the Holy Spirit will be still at work in the Tribulation, for the work of regeneration is His particular ministry. While the work of restraining evil is removed, allowing the Antichrist to begin his evil rise to power, the Holy Spirit Himself will still be in the world and will have an active ministry. While He will no longer be baptizing (for that is a special ministry for the Church only), He will be performing some of His other ministries, such as regeneration, filling, sealing, etc. In all this, the second purpose of the Tribulation will be accomplished: that of bringing about a worldwide revival.1For further discussion of the role of the Holy Spirit during the Tribulation, see [J. Dwight Pentecost, Things to Come: A Study in Biblical Eschatology (Grand Rapids, MI: Zondervan Publishing House, 1958), 263-274].
