Final answer:
Luke 24:49 suggests that Spirit baptism is distinct from and subsequent to conversion, referring to the empowerment from the Holy Spirit after the initial conversion, complementing the Pentecost event in the Book of Acts.
Step-by-step explanation:
The Bible passage that indicates that Spirit baptism is distinct from and subsequent to conversion is a) Luke 24:49. In Luke 24:49, Jesus instructs his followers to stay in the city until they have been 'clothed with power from on high', referring to the baptism in the Holy Spirit which is different and happens after the initial act of conversion. This event is in harmony with the account of Pentecost, where the Holy Spirit descends on the Apostles, which is distinct from the Baptism of Christ by John the Baptist in the Jordan River.
