2 Timothy 3:16
All Scripture is God-breathed and is useful for teaching, rebuking, correcting and training in righteousness, so that the man of God may be thoroughly equipped for every good work.
And yet, the Bible is interpretted differently by every Christian sect. There are some fundamental practices that need to be understood in order for salvation, and many traditions are completely against biblical teachings.
The Bible itself says that it needs to be studied carefully, and also practiced to determine whether it’s true.
Acts 17:11
Now the Bereans were of more noble character than the Thessalonians, for they received the message with great eagerness and examined the Scriptures every day to see if what Paul said was true.
Still, it’s like God wants to make it hard to understand what’s right, given the same biblical text.
BTW, I’m a pretty good student and believer of Biblical Scripture. I’m not here to argue the validity of the bible, so stay away from this thread if you believe in something else and want to argue that point.
