Just start reading a bible (you can find many on the internet, or can be downloaded for free for tablet / smartphone). Start with the NT, not the OT, as the NT is meant for Christians and more for our times. Same as when you would become a doctor. You would start with the latest study books, not the ones used in say 1500.
When you have questions, try to use the internet to find answers from more reliable (unbiased) sources. You can use this forum but there are also a few others that are rather good to help with biblical questions.
Practice your own thinking. Learn to make up your mind, and ideas, and test them. This will take you pretty well where you want to be.
