There IS an absolute truth (John 8:32) ...
I would like to supplement @KenGraham's and @RayButterworth's answers by proposing how this site can work for new Christians like yourself who should be encouraged and applauded in searching for the truth. I hate to see how this site could become a stumbling block for that search, when on the other hand this site can assist a Christian to deepen their faith. I hope my answer below can help you.
I myself, as most of the frequent contributors here, are committed Christians coming from all sorts of denominations who all worship Christ as the Son of God, the Christ (Messiah), our Savior, our Lord and King, the Son of Man who will judge at the end of the world, etc. This is the TRUTH that your quoted John 8:32 talks about (see GotQuestions excellent article What does it mean that “the truth will set you free), but not all kinds of truths. The freedom which John 8:32 talks about is also rather specific: freedom from becoming slave to sin. All denominations and most contributors here are not confused with this primary truth, which is our core identity as Christians.
... but not all truths can be known absolutely.
Unfortunately, even the briefest study of church history in the past 2000 years will uncover many theological options and consequently many doctrines espoused by different denominations. You will see that there are legitimate variations on how the Bible is interpreted. This is simply the fact that any new 21st century Christians have to deal with.
But all Christians agree that a serious Christian will want a local church or a denomination to guide them in conforming our life to the image of Christ. It is a long-term decision similar to how we need to choose whether to trust an MD doctor, a DC (Doctor of Chiropactic) doctor, or a TCM (Traditional Chinese Medicine) doctor, each using a different "doctrine" of practicing medicine. In nutrition, we are also aware of the ongoing debates between different camps of nutritionists whether vegetarian option is healthier, whether a little wine helps, etc. But there is a growing consensus that smoking is bad for us and a growing consensus that all three different medical practice "doctrines" complement each other. Similarly, the question of which denomination is best for my spiritual health can be answered differently by different Christians, although the truth that we need Jesus's death and resurrection is universally held by all Christians.
Will the Holy Spirit help one choose a denomination / church?
There is only One God, One Gospel. There is also One Holy Spirit who helps us believe that
- Jesus is Lord (John 16:13-14, 1 Cor 12:3), and that
- We are children of God (Rom 8:14-16).
(source: John Piper's short interview How Does the Spirit Testify I'm Saved?)
Although the Holy Spirit will guide each of us individually to the "right" denomination, I don't think the Bible promises that the Holy Spirit will provide a believer with the same level assurance that denomination X is the right one as the assurance for the 2 points above. We thus have to combine the promptings of the Holy Spirit with God-given wisdom to discern which denomination can help us best individually to grow in Christ (along with the subset members of the entire body of Christ that belong to that church / denomination).
My hope for you as you begin the journey to find your denominational "home" is that eventually the bewildering options can turn from confusion into a source of riches. This journey is something that a Christian needs to undertake sooner or later (it was a decade-long journey for me).
What this site offers
This site can help one navigate through those options. In today's ecumenical situation, in my opinion there are several legitimate Biblical denominations. This site can help you investigate the various claims of a particular denomination. Which is why, as the other answers point out, the questions and the answers may need to be scoped accordingly. I myself have benefited greatly from this site for my personal search of the denomination I prefer.
If it helps, I wrote an answer on how to deal cognitively with various denominational options, and I welcome your follow-up questions about the difference between being a Christian and Christianity as defined by a denomination in the chat room specifically for this topic. However, those two examples plus thousands of Q & A this site offers should not be substituted with a flesh and blood pastor that you trust! As C.SE makes clear:
Like any library, Christianity Stack Exchange offers great information, but does not offer personalized advice, and does not take the place of seeking such advice from your pastor, priest, or other trustworthy counselor.
It is a paid pastor's duty to guide you in your Christian life and to provide you with a safe place to include personal circumstances that may not be safe to share online, similar to how there is a strict and law-protected confidentiality agreement between us and our doctor / therapist / lawyer.
Growing "head" knowledge to help grow our "heart"
Regardless of which denomination or church you finally can call "home", the Bible is clear that we cannot stay drinking milk like spiritual babies (1 Cor 3:-1-3, Heb 5:11-14). Thus growing in knowledge of the Bible and of a denomination's Christian theology is essential for a mature Christian. Just like in maintaining our bodily health we seek a doctor's second opinion and educate ourselves on good eating and on rudimentary medical knowledge, this site can supplement that maturing in our "head" understanding of Christian doctrines and Bible knowledge, which in turn we use as a "map" to grow spiritually (our "heart").
