Once a person becomes a Christian, he/she receives the Holy Spirit. How does this come about? According to Acts 2:38, it happens after repentance and baptism.

No, Acts 2:38 does not explicitly state that water baptism comes before the baptism or indwelling of the Holy Spirit.

Look again in Acts 10:44-48 and Acts 11:13-18. The order was baptism of the Holy Spirit and then water baptism. Water baptism symbolizes what has already taken place spiritually in the believer.
