What is the Holy Spirit's whole work in the Age of Grace?

The Holy Spirit’s whole work in the Age of Grace is to point lost people to God the Son. For believers, His work is to teach them, encourage them, and reprove them, so that they in turn bring honor and glory to the Son.

Les explains that just as the Holy Trinity works in unison, so Satan, the Antichrist, and the false prophet work together. In the Age of Grace, the Holy Spirit points people to God the Son, and this is the whole work of the Holy Spirit: to point lost people to the Son. For believers, the Holy Spirit teaches, encourages, reproves, and so forth, so that they bring honor and glory to the Son. By contrast, during the tribulation the false prophet causes people to worship the Antichrist, fulfilling a counterfeit role of the Holy Spirit, and both he and the Antichrist are under the control and power of Satan.

What does the Holy Spirit do in the Age of Grace toward lost people?

In the Age of Grace, the Holy Spirit’s whole work toward lost people is to point them to God the Son. That is His entire ministry today: He directs lost people to the Son. During the tribulation, the false prophet will counterfeit this role by causing people to worship the Antichrist.
