ROOTED & GROUNDED
Theology for the thinking Christian | June 10, 2026
You are not merely forgiven. You are inside Christ, and he is inside you. Everything else flows from there.
The Apostle Paul uses the phrase "in Christ" (or its close equivalents: "in him," "in the Lord") more than 160 times in his letters. It is not an afterthought or a rhetorical flourish. It is the load-bearing beam of his entire theology. Everything Paul says about justification, sanctification, adoption, and the final resurrection rests on this single, staggering reality: the believer is united to Christ.
This doctrine, called union with Christ, rarely gets its own Sunday sermon. We talk endlessly about what Christ did for us, and rightly so. But the New Testament is equally insistent on something more intimate: what it means to be brought into Christ, hidden in him, grafted onto him as branches to a vine. Paul's most autobiographical statement of the Christian life cuts right to it: "I have been crucified with Christ. It is no longer I who live, but Christ who lives in me. And the life I now live in the flesh I live by faith in the Son of God, who loved me and gave himself for me" (Galatians 2:20, ESV).
Notice the double movement in that verse. First, a death: the old self, the self defined by its own striving and guilt and grasping for identity, has been crucified with Christ. That verdict is past tense, accomplished, done. But then, life: "Christ who lives in me." This is not Paul's metaphor for moral inspiration, as if Christ were a role model warming his imagination. It is an ontological claim. Christ is actually present within the believer by the Holy Spirit, the source of a life that Paul can only describe by saying it belongs to someone else.
Paul makes this same point at the cosmic scale in Ephesians 1. Before a word of creation was spoken, before the first star was lit, God the Father was already choosing his people "in him" (Ephesians 1:3-4, ESV): "Blessed be the God and Father of our Lord Jesus Christ, who has blessed us in Christ with every spiritual blessing in the heavenly places, even as he chose us in him before the foundation of the world, that we should be holy and blameless before him." Election, then, is not an abstract decree about isolated souls. It is a choosing of persons in relation to a person, in Christ. The union precedes history itself.
John Calvin, who considered this doctrine so central that he placed it at the very gateway to his discussion of salvation, wrote with characteristic precision: "That joining together of Head and members, that indwelling of Christ in our hearts, in short, that mystical union, are accorded by us the highest degree of importance, so that Christ, having been made ours, makes us sharers with him in the gifts with which he has been endowed." Calvin's point is both doctrinal and doxological. Justification is not a transaction conducted at a distance, with Christ on one side of a ledger and the believer on the other. It occurs within a union. We receive the gift because we have first received the Giver. As John Murray put it with equal terseness: "Union with Christ is the central truth of the whole doctrine of salvation."
This has enormous practical weight. The believer who grasps union with Christ does not merely hold a legal status. She holds Christ himself, with all that he is and all that he has done. His death is her death. His resurrection is her resurrection, not only in the future but as a present, operative power reshaping her now. His righteousness is not reckoned to her from across a great distance but because she is, as Paul says, "in him." Suffering, then, is not a sign of abandonment; it is participation in the sufferings of the one she is joined to. Death itself is not a severing of the bond; even in the grave, the Westminster Shorter Catechism notes, the bodies of believers remain "still united to Christ."
This is the mystery Paul calls "Christ in you, the hope of glory" (Colossians 1:27). Not Christ for you (though that is gloriously true). Not Christ ahead of you, waiting at some finish line. Christ in you, now, the very spring of the life you are living this Wednesday morning in June. What would it change about how you go about your day if you took that seriously?
"We do not contemplate him outside ourselves from afar in order that his righteousness may be imputed to us but because we put on Christ and are engrafted into his body. For this reason, we glory that we have fellowship of righteousness with him."
— John Calvin, Institutes of the Christian Religion, 3.11.10

May you go into this day knowing that you do not merely hold beliefs about Christ. You are held, by him, in him. That is the ground you stand on, and it does not shift.
