My favorite devotional bible is the Oswald Chambers One Year Bible. I should call it my Four Year bible, though, as I read one page a day. In it there's both an old testament and a new testament reading with a psalm and proverb in between.
For me, as I look at Genesis abruptly juxtaposed beside Matthew, I grieve all that time before Christ, the countless lives lived before God's hopeful Answer comes to mankind's main problem.
And then there's the countless lives since the fact God's offer of grace in the Cross.
