There are only "2" instances in the N.T. where Baptism (total immersion) of the Holy Spirit occurred, both are recorded in Acts of the Apostles. Acts 2 and Acts 10. The scriptures define 2 types of Baptism......one essential to conversion, water baptism, the other is a Gift as promised by the Christ......called baptism of the Holy Spirit. Both instances were a sign/wonder/miracle to confirm TRUTH. Jesus promised His apostles that a helper would come to lead them into all truth.......that promise was confirmed in Acts 2....Jesus had promised them that He the helper, the Holy Spirit would endow them with knowledge and power from Heaven ........something the World Can NOT RECEIVE (John 14:17).
Find an example where anyone is saved without water baptism.....it does not exist. Some point to the thief on the cross, but Jesus, being God incarnate, saved this man prior to the N.T. perfect law of liberty went into effect after His Death. Thus water baptism is required unless you expect God to personally save you as was the case under the Law of Moses, where animals were annually sacrificed to carry sin over from year to year. There is not one instance where anyone is saved prior to water baptism as required by the doctrine presented by Jesus Christ.
There are but 2 instance of Holy Spirit total immersion...i.e, spiritual baptism in the Bible. One when the Spirit fell upon the Apostles in Acts 2 and another instance when Gentiles were confirmed as being included in the N.T covenant of Christ at the house of a Roman Soldier, Acts 10....but even then Peter reminded them in order to be conveyed into the kingdom of God/Church....the requirement for water baptism must be followed. (Acts 10:47-48)
