Lectionary: Proper 11(A)
Text: Romans 8:12-25
The brain continuously slurps
up huge amounts of energy for an organ of its size, regardless of whether we
are tackling integral calculus or clicking through the week's top 10 LOLcats…
Although the average adult human
brain weighs about 1.4 kilograms, only 2 percent of total body weight, it demands
20 percent of our resting metabolic rate (RMR)—the total amount of energy
our bodies expend in one very lazy day of no activity.[1]
We might assume then that if thinking consumes energy, more
thinking will consume more energy, but the article continues to explain that
experiments in this area have shown mixed results.
But I’m sure we all experience those times when we have been
concentrating on some kind of complex task for an extended period, and at the
end we feel exhausted and fatigued. So, what is a potential explanation for
this phenomenon? The article suggests several possibilities. First,
concentrating on a task that does not bring pleasure causes more experiential
fatigue than concentrating on a similarly complex task, but in which we find
pleasure. Second, merely thinking that a task will be difficult or an ordeal
can cause more mental exhaustion. And finally, unpleasant and complex tasks can
lead to greater stress with corresponding physiological effects such as
increased cortisol production, which in turn can manifest as actual physical
effects.
The article concludes with one of the interviewees saying, “My
general hypothesis is that the brain is a lazy bum… The brain has a hard time
staying focused on just one thing for too long. It's possible that sustained
concentration creates some changes in the brain that promote avoidance of that
state. It could be like a timer that says, 'Okay you're done now.' Maybe the
brain just doesn't like to work so hard for so long.”[2]
An application of this hypothesis to our individual
experiences is regarding habits. Why is it so difficult to break an old habit
and why is it so difficult to establish a new one? Because these take willful,
concentrated, mental effort. And the lazy brain would rather keep running on
easy, well-worn pathways that can be traversed with much less effort.
At this point you might be wondering what this has to do
with any of today’s readings. I think the science of the brain has quite a bit
to do with Romans chapters 7 and 8.
In the latter third of chapter 7, Paul describes an inner
conflict experienced by those who have joined with Christ. The conflict is
between the desire and intention to live a righteous life versus the reality of
falling into deeds that are evil. Paul writes, “Now if I do what I do not want,
it is no longer I who do it but sin that dwells within me. So I find it to be a
law that, when I want to do what is good, evil lies close at hand. For I
delight in the law of God in my inmost self, but I see in my members another
law at war with the law of my mind, making me captive to the law of sin that
dwells in my members.”[3]
However, in the opening paragraphs of chapter 8, Paul describes
the solution to this conflict. “For the law of the Spirit of life in Christ
Jesus has set you free from the law of sin and of death… For those who live
according to the flesh set their minds on the things of the flesh, but those
who live according to the Spirit set their minds on the things of the Spirit. To
set the mind on the flesh is death, but to set the mind on the Spirit is life
and peace.”[4]
But old habits do not die easily. It returns, and in Paul’s
words, it is like a debt that we feel obligated to pay. The old way of living
offers security, certainty, and comfort. The old ways are ingrained in our
minds and require little effort. Even though living by the Spirit brings true
life and peace, it feels easier to return to the old ways.
In response, Paul writes, “So then, brothers and sisters, we
are obligated, not to the flesh, to live according to the flesh—for if you live
according to the flesh, you will die, but if by the Spirit you put to death the
deeds of the body, you will live… For you did not receive a spirit of slavery
to fall back into fear, but you received a spirit of adoption. When we cry, ‘Abba!
Father!’ it is that very Spirit bearing witness with our spirit that we are
children of God, and if children, then heirs: heirs of God and joint heirs with
Christ, if we in fact suffer with him so that we may also be glorified with
him.”[5]
A key to interpreting and understanding Paul’s response is
the phrase, “Slavery… back into fear.” This is the definition of sin
that Paul has in mind throughout his letter to the church in Rome. Fear is what
drives humans to seek certainty and stability in the things of the world:
power, wealth, acclaim, position and influence. These in turn lead to actions
that abuse other humans and the environment. The flesh seeks
self-preservation above all else. The desire for more and the fear that what we
have is still not enough leads to dehumanization, wars, and destruction of the
environment.
To live by the Spirit requires intentional choice and effort.
It requires going against the habits and priorities of the world and how that
has trained our minds and preferences. It will require us to change our ideas regarding
security and stability and where we will find that anchor.
When we live by the Spirit, our focus changes from
self-preservation to selfless giving. It seeks to redeem and preserve all life—not
just fellow humans but all the creation. This is the life Jesus Christ exemplified,
and which resulted in the powers of the world turning against him. It is what
caused them to murder him. It revealed sin—the need for self-preservation
that underlies all worldly powers and structures.
When we choose to intentionally live this way, we will
suffer. We will suffer inner conflict as we seek to retrain the habits that the
world has trained us to follow. We will suffer externally as we walk and fight
against the accepted ways of the world that prioritize the powerful and their
wants over the powerless. When we reject the fear of worldly insecurity and
want, the world ceases to have power over us. And when they no longer have
power over us, they become frustrated and angry.
But we do not live this way alone. Paul wrote, “But you are
not in the flesh; you are in the Spirit, since the Spirit of God dwells in you…
If the Spirit of him who raised Jesus from the dead dwells in you, he who
raised Christ Jesus from the dead will give life to your mortal bodies also
through his Spirit that dwells in you.”[6]
Those of us who are redeemed and being redeemed will
live in such a way as to extend the hope of redemption and restoration to all
the creation. We will strive toward ways of living that bring more harmony and
peace among not just fellow humans, but humans with all the environment without
which we cannot survive. It is with these thoughts that we re-read chapter 8,
verses 18-25,
I consider that the sufferings of
this present time are not worth comparing with the glory about to be revealed
to us. For the creation waits with eager longing for the revealing of the
children of God, for the creation was subjected to futility, not of its own
will, but by the will of the one who subjected it, in hope that the creation
itself will be set free from its enslavement to decay and will obtain the
freedom of the glory of the children of God. We know that the whole creation
has been groaning together as it suffers together the pains of labor, and not
only the creation, but we ourselves, who have the first fruits of the Spirit,
groan inwardly while we wait for adoption, the redemption of our bodies. For in
hope we were saved. Now hope that is seen is not hope, for who hopes for what
one already sees? But if we hope for what we do not see, we wait for it with
patience.[7]
In the name of God, the Creator of all the creation,
In the name of God, the Redeemer of all the creation,
And in the name of God who guides us in our suffering for
all the creation, Amen.
