I'm curious to know how you figured out which denomination you belong to? Did you have to attend many churches and use your own discernment to see if it fits? Is it a must to follow a specific denomination?
God won't be checking your denominational affiliation at the Final Judgment. What will matter then is whether or not He knows you as one of His own. Will you stand before Him as His redeemed, born-again child, or as a rebellious sinner, unrepentant, rejecting the Atonement of His Son for your sin?
Anyway, far, far more important than denomination is the church's fidelity to God's word, to teaching it all with carefulness and faithfulness, seeking the approval of God rather than Man, shining undimmed the light of divine truth in the growing darkness of the World. Does the church add to or subtract from the word of God? You will only know, of course, as you are yourself a careful student of the Bible. Does the church hold to the divine, plenary inspiration of Scripture in its original form? Does God's word have authority over the beliefs and practices of the church, shaping and constraining its life and work? Or does the church approach the Bible like a buffet, picking and choosing preferred bits and pieces of the Bible, ignoring the culturally-awkward parts, rejecting anything that runs counter to the modern social narrative, that defies the present rising philosophies of the World? These are the important questions when considering joining a church community, not "Does this church make me comfortable?" or "Does this church suit my personal preferences?"
My background is really just reading the Bible with little to no outside help. I did get a KJV Bible with Bible study elements to help me understand areas that I don't understand. I do watch a few sermons on YouTube though when I feel that I need to hear a pastor explain scriptures.
If you are a born-again child of God, you have been made a member of the Body of Christ, the Church universal, the family of God, and as such you have been gifted spiritually so that you might benefit the Church and be benefited by it. To remain unattached from the Church is to squander your spiritual gifting to the detriment of the Church, and to starve yourself of the vital fellowship of believers God intends that you should enjoy. The Church - the Bible-believing parts of it, anyway - has an important stabilizing and checking effect on the individual believer's doctrine and living, too, preventing the believer from being "swept about by every wind of false doctrine."
It has been my experience that many (not all) conservative Baptist churches, E-Free, Alliance, Presbyterian, Mennonite, Church of the Nazarene, and mainstream, conservative Pentecostal churches are places where you are most likely to find the fullest and most careful proclamation of God's truth and believers who know and love Jesus Christ in a way that is clearly in evidence in the character of their living.
