How do we know the Holy Spirit is still active today?

The continued activity of the Holy Spirit is witnessed through the regeneration and transformation of believers, as indicated in John 3:5-6, where Jesus emphasizes the necessity of being born of the Spirit to enter the Kingdom of God. Furthermore, the Apostle Paul, in 1 Corinthians 2:10-12, articulates that it is the Spirit who reveals God's deep truths to us, affirming that we have not received the spirit of the world but the Spirit of God. This highlights the ongoing work of the Holy Spirit in illuminating hearts and minds, making the gospel understood and applied to believers' lives. Without the Spirit’s guidance, our understanding of Scripture would be limited, thus demonstrating His persistent involvement in the church.
