In which book of the Bible is the concept of the baptism of the Holy Spirit discussed?

The concept of the baptism of the Holy Spirit is notably discussed in the book of 1 Corinthians. The Apostle Paul addresses the workings of the Holy Spirit extensively in this letter, particularly in chapters 12 through 14. These chapters detail spiritual gifts, the unity of the body of Christ through the Spirit, and the transformative power of the Holy Spirit in the life of believers.

In 1 Corinthians, Paul emphasizes that all believers receive the Holy Spirit upon coming to faith, highlighting the importance of the Spirit's baptism as an integral part of the Christian experience. This theological perspective is crucial as it shapes the understanding of how believers are empowered and guided in their spiritual journey and the communal life of the church.

While the other options contain teachings related to the Christian faith, they do not focus as specifically on the baptism of the Holy Spirit as found in 1 Corinthians. For instance, Galatians discusses the fruit of the Spirit, Romans introduces the Spirit's role in salvation, and Mark includes Jesus' mention of the Spirit's coming but lacks the comprehensive treatment found in 1 Corinthians.
