Again, the Holy Ghost is absolutely promised to those who will be water-baptized in Jesus' Name.
It may not be
the core doctrine in holy scripture; but it is
a core doctrine.
Those who receive this water baptism will be more equipped to minister to those around them because they will have received the baptism of the Holy Ghost as the result of receiving water-baptism in Jesus' Name (Acts 2:38-39).
I am uncertain why it is that certain pastors insist on baptizing in titles when the scripture is clear that
1) water baptism doth also now save us (1 Peter 3:20-21); and,
2) there is none other name under heaven given among men by which we must be saved, other than the name of Jesus Christ of Nazareth (Acts 4:10-12).
Seeing that these two things are true, it should be clear that baptism in titles will not save but that water baptism in the Name will in fact save.
For remission of sins and the Holy Ghost are absolutely promised as the result of receiving baptism in Jesus' Name.
And there is no such promise given concerning being baptized in titles.
Since having the Holy Ghost = salvation (Romans 8:9), I conclude that a person can absolutely secure salvation by receiving baptism in Jesus' Name; since the Holy Ghost is absolutely promised to all those who receive this ordinance.
Those who receive baptism in titles have no such promise of the Holy Ghost.
And even if the Holy Ghost wasn't = to salvation, it might be expedient to receive it anyway; since one can receive power for ministry if or when they receive the Holy Ghost.
Act 1:8, But ye shall receive power, after that the Holy Ghost is come upon you: and ye shall be witnesses unto me both in Jerusalem, and in all Judaea, and in Samaria, and unto the uttermost part of the earth.
