Tim Keller says “This is the best book for laypeople on this subject.” This book is Union with Christ: The Way to Know and Enjoy God by Rankin Wilbourne. I think he is right.
Union with Christ is one of the more neglected doctrines in the contemporary church. This neglect has been addressed with a few releases in the past few years like the books by J. Todd Billings and Robert Letham. These tend toward the more academic or pastoral in nature. Wilbourne’s book is written for the lay person and is easy to understand, though the topic can still stretch our minds. He provides a number of good illustrations to help us understand this rather nebulous concept. Or perhaps enchanted, for in his introduction he relates this to our disenchanted (materialistic) culture, and to understand union we need our imaginations again.
“Coming to see your union with Christ is like finally putting on a pair of desperately needed glasses- Wow!”
He begins with reality of a gap between what the Bible says and our experience of that reality. We can often feel exhausted by our efforts and discouraged by a lack of “progress”. The gap is real and must be acknowledged. But God’s answer to all this is union with Christ.
“First, we must understand that as long as Christ remains outside of us, and we are separated from him, all that he has suffered and done for the salvation of the human race remains useless and of no value to us. Therefore … he had to become ours and to dwell within us.” John Calvin
Calvin, particularly his Institutes of the Christian Religion, is very present in this volume. United to Christ we have all the blessings of God (Eph. 1). Christ also dwells in us by the Spirit so we are empowered by Him to enjoy these many blessings. While this was understood by many in history (he quotes from Edwards and Goodwin, for instance) such talk is like a foreign language to many/most western Christians.
“If it ‘s true that nothing is more central or basic than union with Christ, and this book aims to show that it is, then it is fair to ask this: Why is union with Christ neither central nor basic to so many of us? Why, rather, is union with Christ, if it is talked about at all, reduced to some vague or optional aspect of Christian living…”
The only way we partake of the gospel promises is …. union with Christ. When we neglect this, the work of Christ for us is separated from the person of Christ in us and the gap between beliefs and experience begins to increasingly widen.
He moves on to what it actually is. One aspect of union is imputation: what happened to Him happened to us; what He earned we receive; and what we earned He paid the price for. Paul frequently uses the term “in Christ” to talk about how we live before God. Christ represents us so His death is our death to guilt & sin (Rom. 6; Gal. 2:20). His resurrection is our newness of life (Rom. 6; Eph. 2; Gal. 2:20). His obedience becomes our obedience. We have even been seated with Him at the Father’s right hand (Eph. 2).
“Faith is how union with Christ becomes operative and powerful in your life. Faith is a God-given gift that allows you to take hold of God’s having taken hold of you. … Your life, your story, becomes enfolded by another story- Another’s story.”
As Paul says in Colossians our life is hidden with Christ in God. United to Christ, Calvin says, we receive the double grace of justification and sanctification. Though distinct they are a package deal given simultaneously. We partake of His redemption because we are united to Christ, covenantally and spiritually. We enjoy our salvation as He works in us to transform us. Our faith is not simply in Christ’s work for us, but also that Christ continues to work in us and through us. He became like us to make us like Him so we look to Him to accomplish these things that are so beyond our doing.
Union with Christ also holds together some of the tensions that tend to tear God’s people apart. For instance, he mentions extravagant grace and radical discipleship. We see them both in Calvin’s double grace, but our tendency is to separate them. Apart from discipleship extravagant grace lapses into Bonhoeffer’s cheap grace. Apart from extravagant grace discipleship degenerates into legalism. This conflict that has periodically emerged in the church is resolved in union with Christ. These two songs, as he terms them, meet in harmony in Christ. They cannot be separated because Christ cannot be separated (Ferguson makes the same argument in The Whole Christ). Wilbourne then explains and applies the “double grace”.
“Because we are relentless in trying to justify our lives, because we will use anything, even our virtue, to keep God at a distance, we can’t hear this song of grace too loudly or too often. … That hit home because that’s exactly what I had been doing- using grace as an excuse not to follow Jesus. … Undiluted grace and uncompromising obedience meet in the person of Jesus. He is always full of both.”
Rankin then spends a chapter showing us where all this is in the Scripture, a chapter on where it pops up in Church History (Augustine, Athanasius, Irenaeus, Bernard of Clairvaux, Luther, Owen and Lewis) and then what happened that we have fallen to this low estate. As mentioned, there is the disenchanted or materialistic worldview, the increase in self-centeredness (due to the eclipse of the gospel), our poor pneumatology, sound-bite culture, and pragmatism.
“Paul is saying union with Christ not only gives you a new identity; it gives you a new mindset, a new grid through which to filter everything that happens to you. For it’s not so much what happens that defines you, as how you interpret what happens to you.”
From there he delves into the problems union with Christ solves. We have a new identity, new destiny, new purpose and new hope. So many of the stories we love focus on people seeking to discover their identity. We think we have to establish our identity so we are insecure and exhausted. Many famous musicians (interviews with Madonna and John Mayer come to mind) feel the need to re-establish themselves, prove themselves. In Christ, we receive an identity we neither win or can lose. We don’t have to prove ourselves. This identity also shapes how we live, providing appropriate boundaries for us. We have a new destination too- not simply to decompose in the ground or simply cease to exist. Our destiny is to be what Adam and Eve once were, the image of God. Jesus, in His humanity, the perfect image of God restores God’s distorted image of us. We don’t lose our sense of self (just as in a healthy marriage we are one flesh but don’t lose your sense of self). You become more fully you with the unique gifts and experiences but without the sin and weakness.
“The purpose of the gospel [is] to make us sooner or later like God; indeed it is, so to speak, a kind of deification.” John Calvin
“Because love was central in the life of Christ, love is at the heart of the image of God. Your win is learning how to love. And your greatest losses are your failures to love.”
We are here for holiness, which for many of us, as he notes, is like broccoli. Good for us but …. (personally I like broccoli). Holiness is good, beautiful and attractive. It is something we only pursue properly in union with Christ (see Walter Marshall’s The Gospel Mystery of Sanctification). We are positionally holy due to our union with Christ, and dwelling in us He works to make us personally holy. These two tensions are brought together in harmony in Christ. The more holy we become the more we enjoy communion with God, in part because we now find His holiness more attractive and a greater source of joy.
“God wants us to grow in holiness, not as some sort of test or punishment, not even just as preparation for the future, but because he wants us to enjoy life with him more. The more we grow in holiness, the more we can enjoy his presence. He wants us not simply to press on but to soar. He wants holiness for us, for our joy.”
Our hope is life in the presence of God where Jesus currently is. This is unattainable for us apart from our union with Christ. He is there now, seated and interceding for us (Heb. 7:25). This means that our continuing sin does not separate us from God. We don’t have to look to our circumstances to gauge if God is pleased with us, we look to Jesus and know He is. Union with Christ holds the facts that God with for us and with us together.
“John Calvin said, ‘Let us therefore labor more to feel Christ living in us.’ John Owen added, ‘Labor, therefore, to fill your hearts with the cross of Christ.’ And Jonathan Edwards exhorted, ‘We should labor to be continually growing in divine love.'”
Wilbourne then moves into our daily life as people united to Christ. He begins with abiding. He brings up the illustration of sailing. Sailing depends on the wind, but you still need skills to get where you want to go in the power of the wind. This is communion with Christ, the subjective or experiential aspect of our union with Christ. We cannot be more or less united to Christ. But our sense of communion with Christ grows or diminishes. Faith always precedes our sense of communion for faith lays ahold of Christ. He warns us of our tendency to drift (pride, complacency etc.). If we are not manning the sail and the tiller we will not go where we long to go. He moves into the means of abiding, or the means of grace. Our sense of communion is tied to prayer, meditation on Scripture, and worship including the sacraments (signs of our union). This does not mean all will be exciting. There will be doldrums, just like in sailing. There will be times when all seems stagnant, and no progress is made.
“Jesus lived a perfect life and terrible things still happened to him. Jesus was the only one who ever trusted and obeyed God perfectly, yet he nevertheless was made to walk the way of suffering unto death…”
We are united to the Christ who suffered. As a result we should expect to suffer (Rom. 8; Phil. 1 & 3; 1 Peter 2-4). Because He suffered, He is able to comfort us in our suffering. He also provided an example for us in suffering, to continue to do good and entrust ourselves to our Creator. Will our suffering drive us from God, or deeper into God?
He then moves into the fact that each of us is united not only to Christ individually but also to one another. In Christ we are the people of God. Here, in a footnote, he surmises, that the tension revealed by the New Perspective of Paul finds reconciliation. In Christ we are justified by the imputation of His righteousness AND we are part of the community of God; soteriology and ecclesiology are united in Christ. Another tension that tends to tear the church apart is also reconciled in Christ: we declare and demonstrate the love of God to the nations. Many conservatives so fear the social gospel that they deny the social aspects of the gospel (and throw accusations at any who do). This is because Jesus not just declared God’s love but demonstrated it (see 1 John 3-4) and calls us to do the same (see also 1 Peter 2).
I found this to be a very encouraging book. He had a number of helpful ways to explain our union and its implications. I heartily recommend it to pastors, elders and ordinary people who want to grow in grace. He makes a difficult subject understandable, interesting and practical.
There is a media company that sends me books to review. I choose from titles they make available. Recently they made Costly Grace: A Contemporary View of Bonhoeffer’s The Cost of Discipleship by Jon Walker available. I’ve read 
Walker follows the pattern of Bohnoeffer’s classic book. He starts off with a quote from Bonhoeffer’s chapter, the passage of Scripture used and then interacts with Bonhoeffer. He’s not critical of Bonhoeffer, at least in any significant way. He’s trying to make it more accessible, and in touch with contemporary concerns.
Hard to hear, but I suspect it is more true than we want to believe. Many churches hear messages of moralism and self-help. The broken remain broken, unable to discover the balm of the gospel.
