I will be the first to admit; I find parts of the OT rather drawn out and repetitive, it is hard to read in some places. I also think starting with the book of Genesis would be a way to get the 'whole' picture.
But without sending out alarms, a few other writings also aide to the learning experience. Like the Infancy Gospel of Thomas, although not accredited to be factual, does give a good reminder how Christ was man, flesh and blood, with human weaknesses, but glorious potential. Might I also mention reading the writings of the earliest church theologians like Turtullian, my favorite writing is The Apology by Turtullian.
So in effect, some offhanded writings does help keep one tied to the Word, for His Word is not burdensome, It is rest for the busy soul.
