I used to read through the Bible completely and then reread the New Testament and repeat because I thought the old testament wasn't as important, but the truth is, until you fully understand the first few chapters in Genesis, you can't fully understand the rest of the Bible. Whole foundation is in Genesis.
Being a Christian and an Engineer (and science geek), my passion has become using science to defend the Bible and how Genesis (especially the first 11 chapters, but the first 3 most of all) is the foundation on which our whole understanding of the Bible rests. So many Christians sacrifice the truth and/or clarity of Genesis and then can't stand firm on the rest of the Bible because they destroyed the foundation. Yes, Genesis is literal and true.
