Anyone can baptize you, the bum on the street corner all drunk and reeking of alcohol can do it, what is most important is what it means, or has meant to you, and it should be also seen or witnessed by a few witnesses also, etc, but again, no particular kind, etc, they can be anybody who is just seeing what you are doing, whether they fully understand it or not, is not at all important, etc, just that they see you doing it, etc, but and/or also, etc, I think you are giving Satan way too much credit, and way too much power, etc, and yes, that can be given to him from you, etc, (and can also be taken back away from him by you, etc) (most of it anyway, etc) but, baptism is just between you and God for the most part, apart from what I have already said or told you, etc, you need to know what it meant to you if you have already been baptized, etc, and if you have not yet, then you need to know when you do, etc, and if the prior baptism that you maybe did maybe didn't have the right meaning for you when you did it in the past, but you feel like it would a lot, lot more so now, then maybe you need to do it again, etc, and there is nothing wrong with that, etc, it is primarily only what it means to you that is most important, etc, but it should have great meaning, etc...
And I'll leave others to try and fill you in as to what specifically it maybe may supposed to mean to you or for you or not, or what it represents or is symbolic of, etc, as I'm sure they can give you a lot of ideas about that, etc, but you can also do your own research also, etc...
I know a lot of the atypical answers already, but want to leave some of the work for others to do, etc, that I know they can do, etc...
Some may speak of "two baptisms" maybe also, etc, but again, I'll leave that for them to get into with you, etc...
Anyway,
God Bless!
