By all means, Scripture is given to provide us a written form of His Word.
There are quite a few preliminary doctrines required before chewing meat.
Unfortunately, many of us have been scarred by worldly things and might not have continued in a daily intake of Bible doctrine, resulting in us not being prepared when we are at the right place at the right time to perform a good work through faith in Christ which He has provided for from eternity past.

The notes provided aren’t provided as edict. They are provided for those who enjoy Bible study and are students of history. Every doctrine must be inculcated into the spirit by God the Holy Spirit, not by man. Even with this stated, there is a sizable amount of study notes provided for the serious student who remains in faith through Christ to advance in the spiritual Christian walk with Christ.
