Hi Awkwardsheep!
I think that you've been offered some great advice here. You also bring up some important points too.
There is a need for good teaching in the Body of Christ. There are a couple of passages that refer to this (i.e., Hebrews 5:12; I John 2:27). Teaching is counted among the gifts/roles mentioned in I Corinthians 12:28 -- behind only (first) apostles and (second) prophets.
Sadly, it often feels that there is a famine of good teaching in the Church today. Much of what is passed for teaching is often messages that focus upon postmodern sentimentalities or, sometimes, divisive doctrinal opinions.
Because of this, the best foundational discipleship that you can receive is from personally reading through the Word of God. I don't mean simply going through topical selections or readings. This is because even verses can be carefully selected on the basis of specific personal opinions from those who list such passages -- sometimes using them primarily as a means to a (doctrinal) end.
This is why reading the Bible book-by-book (or even cover-to-cover) is such a powerful thing! When the apostles taught the Word of God, they did so at a time when few people have copies of Scripture. This is one of the reasons why people went to the synagogue. They went to hear the scrolls read aloud.
We now live in a remarkable time where we can have multiple translations of the Bible available on phones that fit in our pockets! In addition, we have access to things like dictionaries, concordances, maps, source texts, etc. -- all on available on that same phone, tablet or computer (even accessible in certain apps)!
My advice to believers (new and more mature) is to search the Scriptures. This was one of the reasons why the Berean Jews were more "noble" than others. They searched (or "examined") the Scriptures to see if what Paul said was true.
When I first became a believer, I read the Bible cover-to-cover. I started with the New Testament, went back to the Old Testament and read through from Genesis through Revelation. My first journey through the New Testament was puzzling. Yet, I understood it more when I went through the Old Testament and then through the New Testament again. I think that I gain new insight each and every time that I read through the Word of God too.
You raise an important point about the need for discipleship. Yet, the teacher of all disciples is the Holy Spirit. He leads us and guides us into "all the truth" (John 16:13). So, with the Holy Spirit as our teacher and the books contained within the Word of God as our texts, we are His disciples. This works even when a local church might not be quite so apt at discipleship.
After all, we have been called out of darkness and into His marvelous light (I Peter 2:9). Where does that light come from? The Word of God! It is really amazing when you consider the words of John 1:1-5.
I've actually received criticism for urging people to read the Bible from cover-to-cover. Yet, it is a good thing to read the Bible from cover-to-cover. It's the basis for all of our doctrines and is sufficient in and of itself to give us a basis for our beliefs. In fact, I like to be pliable enough to lay aside any preconceived notions when I read the Word of God -- willing to receive whatever doctrinal reproof needed as I read through the Scriptures.
Still, I often suggest (with the New Testament) to read Luke and Acts first -- because Luke also wrote the book of Acts. Then, I sometimes read Galatians next (because of Paul's testimony in the epistle to the Galatians). After this, I then read the entire New Testament before shifting back to the Old Testament. So, I essentially prefer to read the Bible this way:
Luke
Acts
Galatians
New Testament (Matthew through Revelation)
Old Testament (Genesis through Malachi)
My wife and I began doing this some time back. We have time set aside each morning where we read the Bible aloud in this manner (followed by praying together). In our case, I read it aloud -- verse-by-verse, chapter-by-chapter -- while she follows along in her Bible. It has been a wonderfully marvelous change compared to our own personal or collective topical studies. We're currently on our fourth trip through the Word of God in this manner.
We also listen to several Bible teachers that focus on the passages that we've read. Now, I don't feel beholden to any particular teacher. After all, they are just fallible men. That said, I do listen to what they say while still cautious enough to know that they aren't perfect in everything. I like to hear individuals like Chuck Smith, J. Vernon McGee, Skip Heitzig, etc. Most of them have their chapter-by-chapter teaching catalog available for free online.
*EDIT - I should also add that I don't mind topical messages or teachings. I just think that these should be in addition to rather than in place of our regular reading through the Word of God. There are some great topical messages available here at SermonIndex (in audio or print form). Someone just posted a great message from Watchman Nee that is very fascinating!
