The Body of Christ is Irreducibly Complex

Among the various camps in the debate between creation and evolution is a set of ideas called intelligent design (ID).  A key part of ID is “irreducible complexity,” a term that comes from the book Darwin’s Black Box, by Lehigh professor Michael Behe.[1]

In short, irreducible complexity argues that evolution by chance, without an intelligent designer driving it, is unreasonable because the multiple systems in a complex organism like a human body – circulatory, digestive, endocrine, muscular, respiratory, and so on – are all interdependent on each other.  The circulatory system alone, with the heart pumping blood through an elaborate system of arteries and veins, is difficult to imagine developing by chance occurrence, but a chance evolution of that system alongside all the other parts it is dependent on is even more far-fetched.  All systems evolving together in lockstep without failing is a much more difficult problem to explain scientifically without a Creator.  The circulatory system takes what the respiratory and digestive systems take in and deliver it to the other systems that use it.  Without the other parts, it has no function and cannot survive and further evolve.

However, my intent here is not to prove intelligent design, but to consider the apostle Paul’s words about the church as the body of Christ.  In 1 Corinthians 12:12, he wrote: “For just as the body is one and has many members, and all the members of the body, though many, are one body, so it is with Christ.”  He continues that no part of the body can say it is not a part of the body because it has a different function than another part (1 Cor. 12:15-16), and also that no part of the body can say it doesn’t need all of the other parts (1 Cor. 12:21).  Those who are in Christ Jesus cannot be divided.

Paul follows his description of the body with 1 Corinthians 13, a powerful statement on the supremacy of love, and in context a gentle rebuke to the idea that a body can survive as individual, unrelated units.  In a human body, any part can only survive by serving the other parts.  Even an organ as incredibly complex and important as a heart cannot survive if it decided to pump blood only for itself.  Where would it get its nutrients?  How would it flee from danger?  As Paul wrote: “If the whole body were an eye, where would be the sense of hearing? If the whole body were an ear, where would be the sense of smell?” (1 Cor. 12:17).  Even an organ as important as the heart is useless in isolation.  It gets its very life and purpose by what it does for the body.

As Jesus said to His disciples in John 13:34-35 – “A new commandment I give to you, that you love one another: just as I have loved you, you also are to love one another.  By this all people will know that you are my disciples, if you have love for one another.

As the song says, they will know we are Christians by our love, and the church Jesus came to build is irreducibly complex.  There is no appendix[2] in the church, which is the body of Christ.  All members are absolutely essential.

Loveless Words

If I speak in the tongues of men and of angels, but have not love, I am a noisy gong or a clanging cymbal.” – 1 Corinthians 13:1

The church in 1st-century Corinth was divided over spiritual gifts, particularly the gift of speaking in tongues.  The apostle Paul wrote 1 Corinthians 13 as a gentle rebuke to the misuse of gifts and the arrogance that came from competing over them.  The first verse above could be paraphrased as “you can be speaking the most impressive-sounding things, but if you’re not saying it to benefit those who hear, you’re just making noise.”

But not just any noise – Paul purposefully chose two specific instruments.  In a symphony, an appropriately timed cymbal or gong has a glorious impact that perhaps no other instrument can match.  However, although you might not catch one bad note from a clarinet, you won’t miss a gong or cymbal played at the wrong time, even once!  To God, the only one with a truly perfect ear, that’s what loveless words sound like.

If even lifeless instruments, such as the flute or the harp, do not give distinct notes, how will anyone know what is played?” – 1 Corinthians 14:7

Render to God

The phrase “render to Caesar the things that are Caesar’s, and to God the things that are God’s” which Jesus spoke in Luke 20:25 is likely a familiar one.  I had a friend in college who worked at Little Caesar’s pizza, and he showed up at Bible study with some pizza from there one night.  We had agreed to split the cost, so when he walked in he said “render unto Caesar!”  We all got the reference and a couple of us laughed (I admit one of them was me).

The “render to Caesar” saying comes from a time where some scribes and chief priests tried to get Jesus in trouble, as they often did, trying any means necessary to condemn Him.  In this case, they first flattered Jesus, trying to catch Him off-guard, then asked Him, “Is it lawful for us to give tribute to Caesar, or not?”  They thought if Jesus said yes, it would upset the Jews who wanted their Messiah to overthrow Rome, and that if He said no, it would upset the Romans and perhaps they would arrest Jesus as a revolutionary.  They thought they had Him trapped, but His answer quoted above was unexpected by them, yet truthful and insightful.

Often the lessons taken from this story have to do with Jesus’ ability to thwart the attempts of His enemies to catch Him in His words, or with the Christian’s obligation to pay taxes, or with something about the relationship between the Jews and Rome.  There are several good applications.

Another important application that’s key to the story, can be highlighted if we shorten the saying to “render…to God the things that are God’s.”  This last part of the quote is where Jesus subtly tells those trying to catch Him that they weren’t giving to God the things they should be.  Although they were the religious leaders of their day, they were focused on the wrong things, like their money and their resentment against the government.  Or even their obsession with arguing with Jesus.

What are the things that are God’s and that we should render to Him?

Paul helps answer this in Romans 12:1, which says “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.”

Here Paul says that the thing we should be rendering to God is our very selves, and Jesus implied this when He said “render…to God the things that are God’s.”  This answer said to the Jews, and everyone listening, that their Messiah wasn’t only going to overthrow Rome, but He was going to overthrow all kingdoms, including those we build in our own hearts and minds.  From an eternal perspective, the many flaws of Roman rule under which the first-century Jews lived were minor inconveniences, including the paying of taxes and other, real abuses.  Jesus wants us to focus on the real challenge: what to do about mankind’s rebellion from God?  This is the real mission of the Messiah.

Luke follows the “render to Caesar” story with a question some Sadducees asked Jesus about the resurrection, also to try and catch Him saying something wrong.  The story was not put there by accident, but in the sequence, I think we see that there is in fact a resurrection, and that our resurrected selves will be much different than our current selves.  Our new selves will be able to perfectly worship God, and we will be able to fully offer our “bodies as a living sacrifice” while we can only do so imperfectly now.

In the meantime, we don’t get a free pass to do what we want because we aren’t perfected yet.  Every day and every moment, we are to “render…to God the things that are God’s” in ways the religious leaders of Jesus’ day (as well as the audience of most of the Old Testament prophets) failed to do.

In closing, I’ll quote the OT prophet Micah, who differentiated between the animal sacrifices of ancient Israel from the “living sacrifice” God requires:

With what shall I come before the LORD,
            and bow myself before God on high?
Shall I come before him with burnt offerings,
            with calves a year old?
Will the LORD be pleased with thousands of rams,
            with ten thousands of rivers of oil?
Shall I give my firstborn for my transgression,
            the fruit of my body for the sin of my soul?”
He has told you, O man, what is good;
            and what does the LORD require of you
but to do justice, and to love kindness,
            and to walk humbly with your God?”  (Micah 6:6-8)

Today, “render…to God the things that are God’s.

Hope’s Anchor

Sometimes we fall into a pattern of trying to rely on our own merit to please God.  We try our hardest to do everything we think He wants us to do in order to earn His love.  We live like the classic hymn “Great is Thy Faithfulness” was changed to “Great is My Faithfulness.”  We put our hope in our own efforts to earn our salvation.

Hebrews 10:23, which says “Let us hold fast the confession of our hope without wavering, for he who promised is faithful” helps explain why we’d much rather have it be “Great is Thy Faithfulness.”  This verse reminds us that He is faithful and is worth putting our hope in.  In contrast we are often unfaithful and disappoint ourselves, falling short of the ideals we strive to achieve.  But we can hold fast to our hope, because it’s based on His promises.

Earlier, Hebrews 6:19 says “We have this as a sure and steadfast anchor of the soul, a hope that enters into the inner place behind the curtain” where “this” refers to the promises of God that were fulfilled by the life of Jesus and give us access to God’s presence.  Counting on our own faithfulness is like being on a ship that attaches its anchor to itself, and the captain wonders why the ship keeps drifting uncontrollably.  So, as the verse says, we must attach our anchor to something else (God’s promises), because an anchor is only as good as what it’s attached to.  Something solid is needed, and God’s promises in Jesus are a solid, unchanging thing we can cling to at all times.

If we relied on our own faithfulness for salvation, every time we disappoint God, we would have to worry about losing our salvation, our place in God’s family.  We would have no security, no way to avoid “wavering.”  Our faithlessness discourages us, but His faithfulness gives us hope and strength.

God is faithful and worthy of our trust.  As the hymn declares about Him:

“There is no shadow of turning with Thee;
Thou changest not, Thy compassions, they fail not;
As Thou hast been Thou forever wilt be.”

We can “hold fast” to Him in all times and in all circumstances.  All of the Old Testament testifies to God’s faithfulness toward His people, and the New Testament testifies to the fulfillment of God’s promises in the life and work of Jesus.  Therefore, His faithfulness is backed up by centuries of history, and through His grace, He offers salvation to His people.  As Ephesians 2:8 says, “For by grace you have been saved through faith. And this is not your own doing; it is the gift of God”. Even our faith is a gift from God, based on His faithfulness, not ours, and given in His grace.  When our faith wavers, His does not.

Therefore, thank God that our hope is in His faithfulness, not in ours.  Our faithfulness is far too uncertain, but through the substitutionary sacrifice of Jesus we inherit Christ’s own merit in the eyes of God and couldn’t please Him anymore no matter what we do.

Let us hold fast the confession of our hope without wavering, for he who promised is faithful

“Great is Thy faithfulness, O God my Father”

The Rebellion at Babel

The story of the Tower of Babel, recorded in just 9 verses in Genesis 11, has a lot more to say than its length might suggest.  It’s not just the story of a tower being built, or a story about the origin of different languages.  It is also a story of why the tower was built and what it meant about the builders’ relationship with God.

The Tower of Babel was mankind’s best effort at achieving salvation, a path to heaven, based on their own works.  In the tower we see man declaring his independence from God, his lack of need for the God, or any god.  This act of rebellion was similar to Adam and Eve’s sinful desire to know good and evil for themselves in the garden of Eden, because the builders of the tower were saying that they know better than God.  “We’ll get to perfection on our own,” they thought.  They were the progressives of their day, believing in the infinite potential of mankind.

Also, verse 4 tells us that part of the motivation for building the tower was to prevent man from being “dispersed over the face of the whole earth,” but God had told His people to “fill the earth,”[1] not to settle down in one spot.  In the next chapter God would tell Abraham that he would become a nation, and that through that nation, “all the families of the earth shall be blessed.[2]  God’s people are not meant to hide in their own dwellings, but to bless the world by telling it of God’s love and by living out that love to “all the families of the earth.”  Babel’s builders had the wrong priorities.

The story of the Tower also tells us that our best efforts will always fall short.  In the story, note that “the LORD came down to see the city and the tower.”  Mankind intended for this tower to reach heaven, but God had to “come down” to see it.  Our best efforts fall way below God’s standards and intention for us.  While we might achieve a lot and take pride in it, it’s never as good as what God can do for us, and we know that “God opposes the proud but gives grace to the humble.”[3]  Later in history, He would show us that only He, in Christ Jesus, could be the path that gets us to heaven.  There is no other way no matter how hard we try.

Another subtle point from the story is that the materials we decide to work with are never better than what God has already given us.  Babel’s builders “had brick for stone,” meaning the tower was built with manmade bricks, not stones.  We might think of stones as “natural” but really, they’re what God created in the form He created it, and they’re much stronger than bricks.  In the same way, if we follow God’s intention for our lives rather than inventing our own ways, we will find that His ways are better and stronger than anything else available.

Lastly, the tower’s very name, Babel, is a form of “Babylon,” which is a literal city, but also in Revelation 17-18 Babylon represents any society where man attempts to live independently of God.  To seek perfection without Him and by His righteousness.  Revelation also tells us that Babylon will be destroyed, and everything that Babylon represents.

God has given us everything we need to live and to glorify Him today.  Will we use it, or try to go our own way?
