Baptism into the Holy Spirit is done by Jesus and we are submerged into the Holy Spirit. A well springing in and up, in contrast to a river flowing out and through. One is salvation and the other is a result of the baptism of the Spirit.
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.
- Acts 1:8 (KJV)
