I sense you might be winding up for making an objection that I am trying to please God through works (forgive me if I'm wrong. Just that you're questions are often set ups),
Just to be clear, many of the questions I ask are intended to focus attention on the implications of something that has been said.
In this case, your comment was that praying in the spirit is necessarily in tongues. My question is that if this is so, and if not all are actually given the gift of tongues, then how do those who are not given tongues able to pray in the spirit?
Your comment was that we can all pray "Spirit-led". But that's not what I'm asking about.
This highlights two distinctions between us. One is the belief in a separate "baptism of the Spirit", and the other being that all receive tongues as a spiritual gift.
I show Scripture that there is only one baptism, and it is into Jesus. You do not wish to discuss it. OK.
1 Corinthians 12
28 And God hath set some in the church, first apostles, secondarily prophets, thirdly teachers, after that miracles, then gifts of healings, helps, governments, diversities of tongues.
29 Are all apostles? are all prophets? are all teachers? are all workers of miracles?
30 Have all the gifts of healing? do all speak with tongues? do all interpret?
31 But covet earnestly the best gifts: and yet shew I unto you a more excellent way.
Do all speak in tongues?
You've separated tongues into two gifts, one of them specifically a prayer tongue.
1 Corinthians 14
1 Follow after charity, and desire spiritual gifts, but rather that ye may prophesy.
2
For he that speaketh in an unknown tongue speaketh not unto men, but unto God: for no man understandeth him; howbeit in the spirit he speaketh mysteries.
3 But he that prophesieth speaketh unto men to edification, and exhortation, and comfort.
4 He that speaketh in an unknown tongue edifieth himself; but he that prophesieth edifieth the church.
I would say that according to this passage that's what tongues is, a language by which to speak to God outside of normal human understanding.
This shows the difference in how you read the Bible and how I read the Bible.
For me, "he that speaks in an unknown tongue speaks to God". It's all prayer.
There is one baptism . . . so there is only one baptism. For you, there are two, unless you mean that Romans 6, baptized into Christ, is the same thing as the "baptism of the Spirit".
Much love!
