First, I focus on what everyone agrees that the Bible says. Ummm, everyone that claims they believe the Bible is true that is. LOL The ten commandments, love God with all your heart, mind, soul and strength and your neighbor as yourself, etc. Things that different "Christian" religions do NOT argue about.
The stuff everyone argues about, I believe that God would have made absolutely and completely clear if He wanted to make sure we didn't miss anything. He even had men write examples where Christians could believe differently and they were not supposed to judge each other about it. What is good for me, may not be good for you, but those things do not contradict the things that everyone agrees on.
For instance, if I go to a country wear women cover every part of their body, I will cover up my body to love them. But if I go to a village where they don't practice marriage and someone wants to sleep with me, I will not commit adultery because that would go against a clear passage of scripture.
I pray and follow what I feel peace about. I don't believe God is a big ugly deity that makes following Him so complicated that people will spend eternity in hell even though they loved Him to the best of their ability but joined the wrong church.
