is one of evangelicalism鈥檚 brightest up-and-coming pastor-scholars. From missions work in Uganda, to a Harvard Ph.D., to an adopted daughter from Ethiopia, Billings is advancing many of the projects dear to evangelicalism. You may have seen his wonderful for Christianity Today (October 2011) on the theological interpretation of Scripture. In November 2011 he published the distillation of nearly a decade鈥檚 sustained reflection on a theme that is central to the gospel: the believer鈥檚 union with Christ.

Billings begins with an account of our salvation in terms of our adoption into union with Christ, an adoption initiated by the Father, grounded in Christ, and applied to us by the Spirit. The four chapters that follow then explore what such an account of salvation means for how we address human sin (chapter 2), know God (chapter 3), seek social justice (chapter 4), and approach Christian ministry (chapter 5).

The has four short video clips of Billings summarizing these themes. So I鈥檒l just burrow down into one chapter in an attempt to give the flavor of the whole.

The strategy here is reminiscent of one of the few things I remember from my undergrad days. When you want to test a math equation, you test its boundary conditions. What does it do when you give it nothing? What does it do when you give it everything? In the automotive analogy, what does the car do when you floor it, when you slam on the brakes, when you pull a hard left at 30mph? Billings鈥檚 book is clearly aimed at the practical implications. So I figured that if he could do something relevant, practical, and engaging with the chapter that has 鈥榤ystery鈥 and 鈥榠ncomprehensibility鈥 in the title (chapter 3)鈥攊f Billings could be practical here, the rest would be easy.

And he is. So what does our union with Christ mean for how we know God? A biblical account of knowing God will have to speak both of God鈥檚 transcendence (so there鈥檚 stuff we can鈥檛 know about God) and his immanence (so there鈥檚 stuff we can). God is only 鈥榗omprehensible鈥 (entirely knowable) to himself; to us he is 鈥榠ncomprehensible鈥 (not entirely knowable, partially knowable鈥攂ut not unknowable!). But it is God himself who has seen to it that we can have true and important partial knowledge of him. And he has done so by addressing us and becoming one with us in the Son. When the Father then unites us with the Son by the Holy Spirit, we begin to share in Jesus鈥 own human knowledge of the Father. So both now and in glory, the way God enables us know him is not ultimately by filling our brains with information about him. The Father lets us see him as only Jesus can (87-88). What an amazing privilege!

Now on the way to this conclusion, Billings explores patristic apophaticism and the nuances of Calvin鈥檚 eschatology and the account of archetypal and ectypal knowledge in (some guy I鈥檝e never heard of named) (1545-1602). We meet biblical theologians like (1616-83) and (1854-1921) and modern theologians like (1925-2011) and (1933鈥). Of course, I love this kind of stuff. But it鈥檚 all in order to secure the basic point that everything we will ever know about God, from whatever source鈥攊t all comes not as human achievement but as divine gift. That鈥檚 a lot to be thankful for. Cool, eh?

鈥淲ait a minute, Price. What happened to 鈥榬elevant鈥 and 鈥榩ractical鈥? I want to know what this means for me.鈥

Well, OK. How about this. We only know God because he has accommodated himself to our slender, human capacities, right? Billings asks the probing question: Do we value God鈥檚 loving act of stooping down to us in the incarnation? Do we like God鈥檚 stoop? Calvin speaks of God babbling to his little human creatures like a mother babbles to her infant (). How well do we think God babbles? According to Billings, many who focus their ministries on supposedly making the gospel 鈥渞elevant鈥 to culture are in fact attempting to find some other way than Jesus, as he is revealed in Scripture, to help people know God. Such ministry strategies suggest that God is a bad babbler or an insensitive seeker. 鈥淚f we are to have genuine communion with God, we must meet God [as he] accommodates himself to us in Scripture and most fully in Jesus Christ rather than seek to climb the ladder of self-devised analogies toward the mysterious God鈥 (93). The point is that enabling people to know God is something that only God himself can do, and that God himself has already done鈥攑erfectly, unsurpassably鈥攊n Jesus and Scripture. We ignore this at our ministerial peril.

So and spend a little time meditating with Billings on the gospel of our union with Christ. It鈥檚 hard to beat a book that鈥檚 exegetically, historically, and theologically rich, clearly written, pastorally sensitive, culturally engaged, generous in tone, practical鈥攁nd short!
