Often when it has come to Children Bibles i've found them to be simply a book of stories, having no real thread connecting them.

However . . . dun dun dunnnn . . . The Big Picture Story Bible entered our home.
I'd heard of this book through Albert Mohler's review quite some time ago & though filed at the back of my mind it seemed to fall out one day as i browsed Amazon and came across it. After reading more reviews it was promptly ordered.
I unwaveringly recommend the Big Picture Story Bible to fellow parents of, even young children as a means to help them grasp the constant redemptive theme of the Scriptures. It doesn't shy away from dealing with death, punishment or sacrifice.
For a great review of this book visit Kingdom People. I absolutely second everything Trevin Wax says about it.
On a sort of negative note a friend who had this Bible for their kids found the binding to be of poor quality and theirs fell apart. However they have considered buying a new one - so i guess that is a recommendation of sorts!
