I appeal to you therefore, brothers, by the mercies of God, to present
your bodies as a living sacrifice, holy and acceptable to God, which
is your spiritual worship. ² Do not be conformed to this
world,but be transformed by the renewal of your mind, that by testing
you may discern what is the will of God, what is good and acceptable
and perfect. ³ For by the grace given to me I say to everyone
among you not to think of himself more highly than he ought to think,
but to think with sober judgment, each according to the measure of faith
that God has assigned. ⁴ For as in one body we have many
members,and the members do not all have the same function, ⁵ so
we, though many, are one body in Christ, and individually members one
of another. ⁶ Having gifts that differ according to the grace
given to us, let us use them: if prophecy, in proportion to our faith; ⁷ if
service, in our serving; the one who teaches, in his teaching; ⁸ the
one who exhorts, in his exhortation; the one who contributes, in generosity;
the one who leads, with zeal; the one who does acts of mercy, with cheerfulness.

Our focus today is on Romans 12:4-6a, namely, on the foundation and
nature and implications of being one body in Christ. Keep in mind the
bigger picture. Paul has spent 11 chapters teaching us the gospel of
Christ—that we are great sinners, that God is infinitely holy and just,
that we are therefore under his wrath and condemnation, but that God,
in his great mercy has sent his Son Jesus Christ whose perfect obedience
and death in our place makes it possible for God to justify—declare
righteous—all who trust in Christ, so that there is therefore now no
condemnation for those who are in Christ Jesus.

And on the basis of that great work of salvation for all who believe
in Christ he now begins to build his application for life in chapter
12. “I appeal to you therefore, brothers,by the mercies of God . . .”
In other words, the Christian life is built on the mercy of God. We
are not a people trying to earn the favor of God. We are people who
are stunned that we have been shown utterly undeserved favor mercifully
because of Christ. We do not try to earn mercy with a merciful life.
Instead we are able to live a merciful life because we have been shown
mercy.

So chapter 12 begins to describe this life and call us to it. First
Paul deals with our life as worship toward God. Then he deals with humility
and lowliness in relation to ourselves (v. 3). Then he deals with our
relations with each other in the church (vv. 4-13). Then he deals with
our relation to our enemies (vv. 14-21). Then he deals with our relation
to the civil authorities in chapter 13:1-7 and so on. All of this is
what life looks like when you know that you have peace with God by faith
alone and Christ has become the foundation and summation of all your
hopes.

So focus with me on verses 4-6a. I see three points to make about
the church as the body of Christ and two applications to our situation
today. The first point is that the unity of the body of Christ is created
in Jesus Christ. Second, individuality is valued in Christ. Third, God’s
grace sustains all ministry in Christ. And the two applications are
these: First, intentional commitment to racial harmony and ethnic diversity
in the body of Christ is implied here; and second, participation in
a small shepherd group helps us fulfill God’s vision for us as a mutually
ministering body with varied gifts. That’s the outline. Now let’s go
to the Scripture and see these things.

1. The Unity of the Body of Christ Is Created in Jesus Christ

First, the unity of the body of Christ is created in Jesus Christ.
Let’s read verses 4 and 5a and stop with that tremendously important
little phrase “in Christ.” “For as in one body we have many members,and
the members do not all have the same function, 5 so we, though many,
are one body in Christ.” We, though many, are one body in Christ.

When Paul speaks of the church as a body he moves back and forth
between two meanings that overlap. One is that the universal church—every
believer in Christ who has ever lived—is the body of Christ. For example,
Ephesians 1:22-23, “He put all things under his feet and gave him as
head over all things to the church, which is his body, the fullness
of him who fills all in all.” That’s the invisible, spiritual, universal
church of all believers, the body of Christ. But the other meaning is
that that Paul thinks of each local church as the body of Christ
as well. For example in 1 Corinthians 12:27 he says to that church,
“Now you are the body of Christ and individually members of it.”

I don’t think he wants us to draw a hard line here. So when he uses
the word “we” here in verses 4-5—“We have many members . .
. we are one body . . .”—even though that includes himself
hundreds of miles away, I don’t think he means to say, “We are only
talking about the universal body of all believers, not your local body.”
I think he is referring to how that local church should function as
a body, and yes, I am in a larger sense a part of you all in
Christ.

What Does It Mean to Be “In Christ”?

The phrase I want us to focus on is the phrase, “in Christ” in verse
5a: “so we, though many, are one body in Christ.” What this
phrase means is that the interwoven unity of all the members into one
body is created and brought about in Christ. One simple way
to say what that means is that as each of us is in relationship to
Christ, we are therefore in relationship to each other. If I am Christ’s
brother, and your are Christ’s sister, then you are my sister. By creating
relationships with himself, Christ creates the relationships in the
body.

But the truth here is deeper than that. What it means to be “in Christ”
far more profound than the human analogy of family relations suggests.
That would be precious enough. But it’s far more and far better than
that.

What this phrase “in Christ” means is that when you trust Christ
as your Savior and Lord and Treasure (Philippians 3:9), a union is established
between Christ and you in such a way that everything in Christ that
can be shared will be shared with you. Everything that he is, and
everything
that he has that can be shared will be shared with
you. And there is only one thing that can’t be shared—his deity, and
its unique God-defining attributes (like omnipotence and omniscience
and eternality). But everything else that Christ is and has is yours
in him.

Consider a few examples from the way this little phrase “in Christ”
is used. This is what it means for you to be “in Christ”:

• 1 Corinthians 1:4, we receive grace in Christ.
• Romans 3:24, our redemption is in Christ.
• Galatians 2:17, we are justified in Christ.
• Ephesians 4:32, we have forgiveness of sins in Christ.
• Romans 8:1, there is no condemnation in Christ.
• 2 Corinthians 5:17, we are a new creation in Christ.
• Romans 6:23, we have eternal life in Christ.
• Philippians 4:19, God supplies all our needs in Christ.
• Ephesians 1:3, we have every spiritual blessing of heaven
  in Christ
• Colossians 1:28, we will be presented to God perfect in
  Christ.
• Romans 8:32, we cannot be separated from the love of God in
  Christ.

Paul’s aim in talking this way is that we stand in awe of Christ.
That we love Christ, and admire Christ and follow Christ and enjoy making
much of Christ above all things.

Paul has not departed from his passion in verse 3 to keep us humble
and make Christ great. Listen to the way he relates this truth to boasting
in 1 Corinthians 3:21-23, “Let no one boast in men. For all things are
yours, whether Paul or Apollos or Cephas or the world or life or death
or the present or the future—all are yours, and you are Christ's, and
Christ is God's.”

You belong to him. You are in him. There is a union by faith so that
all that he is, he is for you. It is simply breathtaking. Oh, that God
would help us believe it with all our hearts.

And the only thing—and it is a huge and wonderful thing—to be added
from Romans 12:5 is that we experience all of this together in
one body. “So we, though many, are one body in Christ.”  Redeemed
together. Justified together. Forgiven together. Created anew together.
Every need met together. Loved by God together. Perfected together.
Living forever together—and all of this glorious unity created in Christ
and for the glory of Christ.

Oh, let us never trivialize the church! It cost God the life of his
Son to create this. And what you share with the persons sitting near
you in Christ is a life and an inheritance and a union so great and
so profound that it surpasses the value of all other human relationships
and all inheritances and can never end.

That’s the first thing to see: The unity of the body of Christ is
created in Jesus Christ .

2. Individuality Is Valued in Christ

Second, individuality is valued in Christ. Look at verse 5 again
and focus on the second half of the verse: “So we, though many, are
one body in Christ, and individually members one of another.”

One could ague that Paul’s focus here on the individual is really
to stress that each of us is part of the collective unity called the
body and that each of us is connected with every other member of the
body. So one might say: There is no effort here to emphasize the value
of individuality, but the contrary, to say that the body is all that
counts.

But in view of verses 6-8, I don’t think that would be right. Verse
6 says, “Having gifts that differ according to the grace given to us.”
That is a conscious effort to make explicit our individual differences
created and willed by God’s grace. Then he spells out different gifts
in verses 7-8. So it would not be fair to say that Paul is trying to
minimize our individuality and only emphasize the corporate reality
of the body.

Would it not be better to say it this way: Paul is saying that our
true individuality is found—discovered, experienced—in relationship
to the body of Christ. Think about verse 5b, “and individually members
one of another.” Members (parts) of one another. One by one. Individually.
Here’s what Paul is saying: I am part of you. You are part of me. I
am like your eye or your ear or your hand or your foot. And you are
like my eye or my ear or my hand or my foot. Each individual, Paul says,
is part of the other individuals in the body.

Here is the amazing thing: That’s who I am. I am a
part of you. Which means that my individuality—my individual identity,
as God has created me to be—cannot be known except in serving you as
I rely upon Christ. And yours cannot be known except in serving others
in reliance on Christ. That’s what hands and feet and eyes and ears
do. They serve. That’s why we have gifts.

Paul values individuality so highly that he does not fail to tell
us how our true individual selves can be known, namely, by living in
relationship others and by serving and being served in the body of Christ.
And then from that position and identity (as we will see later in the
chapter) we express our individual identity with Christ in relation
to the world. Love other people with all your heart in reliance on Christ
and you will discover who you are.

So, the first point was that the unity of the body of Christ is created
in Jesus Christ. And the second point was that individuality is valued
in Christ—indeed, discovered in the body of Christ.

3. God’s Grace Sustains All Ministry in Christ

Now, third, God’s grace sustains all ministry in Christ. We saw this
last time, and so I will only point it out and close with two applications.
Verse 6: “Having gifts that differ according to the grace given to us.”
What we are in our differing individuality we are by grace. You may
not think so. You may not approve of what God has made of you for the
sake of his body. You may think he made a mistake. Or that he is cruel.
I don’t think that is mainly a self-esteem issue. It’s mainly a God-esteem
issue. Will you trust him—that your individuality is a work of grace.
You are a gift of grace to the church. You will find that when you start
loving the church in practical ways.

Two Implications

Now, two implications. The first has to do with racial harmony and
ethnic diversity in the body of Christ. Listen to Ephesians 3:6 as Paul
draws out the ethnic implications of being in Christ: “The
Gentiles
are fellow heirs [meaning: with the Jewish believers], members of the
same body, and partakers of the promise in Christ Jesus through
the gospel.”

What that means is that the unity of the body of Christ created in
Christ includes the nations. All the races and all the ethnic groups.
By coming into union with Christ, they come into union with me, and
you. And since Paul doesn’t make a fixed distinction between the body
of Christ locally and the body of Christ universally, that has implications
for us here.

What it means very simply at Bethlehem is that we think this reality
should be visible in our church. God is sovereign, and God is gracious.
He positions his people as he wills. We are not the final builders of
the body of Christ. But what it does mean is that we steadily—and with
faith and hope—pray toward and work toward ethnic diversity and harmony
in Christ in this church. We think it is a great honor to Christ. I
invite you to join us in this prayer and this work.

The final application of this message is that we believe your participation
in a small shepherd group will help you become who God created you in
Christ Jesus to be, and will help us fulfill God’s vision for us as
a mutually ministering body of believers with varied gifts. The biblical
picture is clear: to be a Christian—to belong to Jesus Christ—is to
be part of his body and “individually members of one another.” This
is why we have small groups, and why we work hard to help you find one
that frees you to serve and be served in relationships of love.

It is an amazing calling and an amazing identity: being the body
of Christ and individually members of one another. There is more to
be discovered about yourself in Christ than you ever dreamed. And Christ
will be more and more honored by every discovery you make.
