How do we know the Holy Spirit is our guide today?

The Holy Spirit's role extends beyond the day of Pentecost; He continually works within believers to convict them of sin, righteousness, and judgment. This is evident in the way Peter preached after being filled with the Holy Spirit. A true indication of the Holy Spirit's presence is not seen in miraculous signs, but in the proclamation of the gospel, which glorifies Jesus Christ. Those who are filled with the Spirit will speak of Christ and His work, leading others to conviction and faith in Him. Thus, the Holy Spirit remains active as the guide, teacher, and comforter in the lives of believers.
