Reading the bible can be complicated and overwhelming especially if it is your first time. You can expect that all of the things will be very hard to understand especially if you are planning to read from cover to cover. The best thing that you can do is to join a bible reading program. It will allow you to read the bible in portions.
If there are some things that you did not understand about the portion that you have just read, you can read it again. It will allow you to understand the story better. It may also open your insight about your whole situation.
