Johah,
If you want it, God will give it to you. Your desire is genuine, so I suggest you read the Bible often. For right now, I would stick to the New Testament and study the Old Testament when it is referenced to. I love the Old but you live in the New, you have time to study it as you go. Learn what it means to be under the New Covenant and not the Old Covenant...what are the differences? There is so much to learn, but as you progress many of your concerns will go away.....something else to learn is that it is not your faith that you must manufacture, it is your faith alright but God gives it to you as a free gift.
Keep at it, you are hear for a purpose...welcome!
