You just cannot pick up any old kind of bible or study bible that a man has stamp his name on it with their footnotes and reference notes. Then you want to teach truth. You also must know the language of the Bible and the style it is written, and you do not have to go to a seminary. Only thing you need is a excellent King James Version. With explanations, and references. It will tell you right at the verse, and how it is writte. example: ( now this is not in the original scripture but they added this to the Bible because.....etc). Then you will "oh" I understand. Then you keep on reading. Or this word was replace because..... etc but the real word is this. Then you say "oh"..... then you keep on reading. This continue through out the Bible. Then sometimes a whole portion was added in earlier versions but never I say never written in the original text, but was added, it tells you this as you read along. But it is written there. Yes it takes a long time to read. But through out the years, it becomes a part of you. But now days I can see why many who want to be serious in their studying the Bible have a difficult time arriving there, but with the help of God you will. "for the devil is very busy in his world" to make it hard for you to know the truth of the Bible. In so many cases. The devil can leave out a comma in God's Word, that leads to the wrong truth! Or make you think a italicize word means nothing, so what do you do with one, just keep going and ignore it? And if the Bible word is in brackets, or parentheses, square brackets, These are the simple things but important. To be the serious student or as the Bible says a "disciple". Consider these things. It depends upon you. If you are physically able.
