How do we know the Holy Spirit baptism is not a second work of grace?

The belief that Holy Spirit baptism is a second work of grace is not supported by Scripture, which presents Holy Spirit baptism as a unique event facilitated by Jesus during Pentecost. Acts 2:1-4 describes how the Holy Spirit descended upon the apostles, empowering them for the church's mission. This singular event demonstrates that Holy Spirit baptism is not something believers experience repeatedly; instead, it occurred when Jesus inaugurated the New Testament church. Paul clarifies in 1 Corinthians 12:13 that all believers are baptized into one body by the same Spirit, emphasizing that our entrance into the body of Christ through water baptism signifies that we are unified under one Spirit, not through successive works of grace.
