Hey OP! I actually got to an IFB church, I used to be Catholic.
As I’ve witnessed these types of Churches are very traditional and the people of these churches actually love God and practice the Teachings of the Bible. I have been to other protestant Churches and none are like it, I have even found a woman my age who loves God as much as I do, so I even have hope of marriage through them!
How ever these churches are pretty strict, and if that makes your uncomfortable or gives you spiritual doubts then I would say be patient and really look for one that is able to guide you, all the IFB Churches are slightly different and none perfect.
The one I go to has actually convicted me on abstaining from drinking and smoking ( cigs ), and I am determined to see it through!
I hope you actually do check them out, prayers and good tithings to you brother.
