Water baptism and Holy Spirit baptism are ordained by God.
Yes scripture agrees that water baptism is a symbol or a figure of death and resurrection, but it isn't just getting wet. It's the answer of a good conscience toward God according to Peter and part of fulfilling all righteousnes according to Christ (Matthew 3:15).
