Teachers, are great.
I love teachers, who are able to go verse by verse, and explain to you what is going on in context, and in the scenario of the who, what, why, when, and how format. Who can really teach you something about the bible in it is context, by the help of the holy spirit teaching the best we can as we can see from scriptures. Even looking up some history can help us understand more.
There are many teachers out there though, and many different studies. This link shows all the different studies that are made in Christianity to this day,
But there are many Denominations and Sections of Christianity.

There are many different studies performed, also there are
Calvinism believers who take their own things they believe and apply it how they teach.

Don't know really believers who take their own things they believe and apply it how they teach.
Preterism believers who take their own things they believe and apply it how they teach.
Pretribulationism believers who take their own things they believe and apply it how they teach.
Mormonism believers who believe and take their own things they believe and apply it how they teach.
Jehovah witness believers who believe and take their own things they believe and apply it how they teach.
Just making a generalization.
Teachers are great. You may not agree with their own views (and that is okay), but if they dont understand something or have questions about something and youre a believer in the Lord Jesus Christ, you can help them with those questions to help them have clarity. (Kinda like with the Mormons, and Jehovah) Correction out of Love if they needed help seeing.
We all know that salvation is faith alone in the Lord Jesus Christ, and thank God, He made it so simple as to believe on to believe on Him, who came, died, and rose again, that if we believe this on heart, and call out to the Lord Jesus Christ in having a relationship we shall be saved, and it goes for anyone who turns to the God in a change of mind or repentance.
Turning to God, and the Lord Jesus Christ changes us from the old person we once were into a new creation, and we was loved before even while we were still sinners Christ, died for the ungodly. That because of everything the Lord Jesus Christ has done we can have direct connection to to Him, and His Father in supplication, and praying, and thankgiving.
1 John 3: 23 and this is His command, that we may believe in the name of His Son Jesus Christ, and may love one another, even as He did give command to us,
God bless friends!
