Hi Scott,
Welcome to CFS.
I'm glad you are making an effort to read and understand the Bible. Sometimes it takes a lifetime for some people to just start reading it. You are definitely a lucky one to realise this at this age.
Beginner?
You can start of from the New Testament where the story of Jesus Christ actually begins. Mathew is the first chapter.
Whenever you start reading the Bible, start off with a simple prayer to God, asking Him to help you understand each and every verse. Believe me, this has worked for a lot of people I know. The Bible will change your life, if you make sure you read and follow it everyday.
Is there some part for which you need explanation? Post it here. I'll be glad to help you
