AI OVERVIEW: Three baptisms are described: a spiritual baptism into Christ that brings salvation, a water baptism that publicly identifies a believer with Jesus and leaves the old life behind, and a Spirit‑and‑fire baptism that empowers for witness. The Spirit’s work moves from creation—bringing order and light after God speaks—and then fills the church at Pentecost, enabling believers to speak in tongues and to testify to Jesus with power. The sequence is clear: belief in Jesus, water baptism, and then Spirit baptism to receive strength to live for Christ and to reach others, as seen in Acts 2, 8, 9, and 19 and in Mark 2:22.
