Our church has a small bookstore of good, meaty books. Recently our pastor highlighted The Jesus Storybook Bible and I bought a copy for our little guys. It's excellent, and perfect for the 3-6 (maybe older?) crowd. An older reader would certainly enjoy it; our 9-year-old has been reading it to herself.
Jesus. From Genesis to Revelation, He is the story. When our children grow up understanding that our salvation based upon Christ's death and resurrection is one beautiful threaded story from the beginning to the end, then they will see their Bible and its content in a whole new light.
I have one to give away! Comment here before January 30th, 2011 at midnight PST, and I'll pick a winner at random.
