“The Armor of God”
Text:
Ephesians 6:10-20; Mark 7:14-23; Psalm 51 (Introit)
Grace, mercy, and peace
to you from God our Father, and from our Lord and Saviour
Jesus Christ.
Amen.
Most people know of the story of David and
Goliath. They know of the story. But they don’t know the story.
What they know is the little guy beats the big guy. And that has become a
well-known image in our world today. David beats Goliath. The underdog wins.
The winless team beats the undefeated team. The small neighborhood store beats
the big national chain.
But there is much more to
this story than that. Because this is not really a story about the little guy
winning, as it has become known and used in our world today. It is about God
fighting for His people, and faith in God, that He will do so.
And so an important part of this story is that
when David insisted on going out to fight Goliath, and King Saul finally gave
in, Saul put his armor on David - a helmet of bronze, a coat of mail, and a
sword. But David had never worn armor before and couldn’t fight like that, with
all that on him. It wouldn’t work. So He went with a different kind of
armor to protect him - the armor of faith. Faith that
God would fight for Him and protect Him. Something the armor of this
world would not and could not do. So David tells Goliath: I come to you in
the name of the Lord of hosts, the God of the armies of Israel, whom you have
defied. This day the Lord will deliver you into my hand (1 Samuel 17). And the Lord did. You
know the rest of the story.
So, armor. What armor are you wearing? How
are you trying to protect yourself? So you don’t get hurt. So your secrets and
sins don’t get out. So the sins of others don’t get in. So you’re not
vulnerable. We all do it. Put up walls, defenses. Armor.
We try to be strong. We try to protect ourselves. We try to save
ourselves.
That’s what we heard last week in the Gospel,
with the Pharisees and their traditions and laws. They thought that by doing
all the right things in the right ways, and even more, they could
protect themselves and save themselves. Keep sin out. Keep sin at bay. Keep themselves pure. The traditions and laws were their armor
against the Goliath of sin and evil.
And we see this kind of thinking still today,
with the religions of the world, like Islam. That with the right laws, with the
right traditions, with the right armor, they can save themselves. So, for
example, with Islam, according to their law, Sharia law, women
have to wear a burqa, a head to toe covering of their bodies, sometimes even
with a mesh covering their eyes. This is so men will not look at them
perversely; so there will be no lust in their heart. But it doesn’t work.
You may remember when Osama Bin Laden was killed and the military was going
through the things in his house looking for intelligence, they found a trove of
pornography. He couldn’t keep that sin out.
And Jesus today tells us why that is; why this
kind of armor doesn’t work. After
sparring with the Pharisees, as we heard last week, He continues today with His
teaching on this. He says, basically, that it’s not what’s outside of us
that’s the problem, because sin and evil are already
inside you, in your heart. If your house is infested with termites, you
can stop more termites from coming in, but the ones already in are going to eat
your house apart. If you have a computer virus, you can stop other viruses from
infecting your computer, but you still have to deal with the one that’s already
there. So it is with the human heart, Jesus says. The sin is already there.
Therefore all the armor, walls, and defenses you put up don’t work. Watching
pornography doesn’t make you lust; this lust already in your heart makes
you watch pornography. Stealing doesn’t make you greedy; the greed already
in your heart makes you steal. Disobeying your parents doesn’t make you
rebellious; the rebellious nature already in your heart makes you
disobey. All of which is to say, it’s not your sinful deeds that make you
sinful; it’s your sinful heart, your sinful nature that produces and shows
itself in sinful deeds.
And so, Jesus said today, What
comes out of a person is what defiles him. For from within, out
of the heart of man, come evil thoughts, sexual immorality, theft, murder,
adultery, coveting, wickedness, deceit, sensuality, envy, slander, pride,
foolishness. All these evil things come from within, and they defile a person.
This is also why something like monasticism doesn’t work. Monasticism isn’t
wrong, per se, but it also doesn’t make you holy. You can take a vow of silence
and still think evil thoughts. You can take a vow of poverty yet still think of
money and wish you had more. You can take a vow of chastity and still lust and
have impure thoughts. You can be alone and still hate.
The armor David tried to wear, the armor of the
laws and traditions of the Pharisees, the the burqas
of Islam, the walls of a monastery - none of it works. None of these are inherently
bad, but they cannot cleanse the heart. We need a different kind of armor, the
armor David did go into battle with - the armor of God. Because
as Paul said, this is a different kind of battle. A spiritual
battle. Even the battle with Goliath was a spiritual battle. And we
need to think that way today. That, as Paul said, we do not wrestle
against flesh and blood, but against the rulers, against the authorities,
against the cosmic powers over this present darkness, against the spiritual
forces of evil in the heavenly places. The battle is greater than we
think. So are the stakes: eternal life or eternal death.
So Paul describes different armor and different
weapons for us today: truth, righteousness, the gospel of peace, faith,
salvation, the Word of God, and prayer. These are things that may not
look very strong or seem very powerful, but only if we are thinking of the
battle wrong. But these are the very things satan fears. Your walls, your armor, your
strength, your efforts - he loves those! Those are a
joke! He can get around them and over them and under them and through them
easily. You know it. He has for you. But the weapons and armor of God are his
kryptonite.
So, Paul says, Put
on the whole armor of God. Or another way to say that is: put
on Jesus. He is the armor of God. He is the truth, He is the righteousness
of God, He has made peace for us with God, He is the object of faith,
He is the salvation of the world, the Word of God incarnate, and
the one who prayed for us and through whom we now pray. We are clothed -
armored! - with Christ when we are baptized (Galatians 3:27). And when we are
baptized our hearts are cleansed and the Spirit given to us. When we repent we
are again washed, not outwardly but inwardly. And the Body and
Blood of Christ are that food that are not eaten and expelled, but that
nourish us and work in us to expel the sin and evil that live in us. This
is the armor we need. These are the weapons that win. Just ask Goliath. Oh
wait, you can’t!
So let’s ask David instead. Yes, he’s dead, but
we heard from him today, in the Introit, from Psalm 51, the psalm he wrote
after his adulterous and murderous affair with Uriah the Hittite’s wife. David
slew Goliath, that was great! But later, the sin and
evil in his heart slew him. And when God showed him
that sin and evil in his heart, just as Jesus talked about today, it crushed
him. It brought David to his knees, and he prayed (as we sang): Create
in me a clean heart, O God, and renew a right spirit within me. He was
desperately sinful and unclean, and only God could rescue him, save him, make
something of him, create in him something from nothing. Because when God
creates, it’s always from nothing. We can’t do it, but God can.
And God did. Yes, for David, but even more, for
all people. That’s what the cross is all about. On the sixth day, God had
finished His creation; and on the sixth day, a Friday we call good, Jesus finished His work of atonement and re-creation.
It is finished, He said. And then just as in the beginning, He rested on
the seventh day, in the tomb. But then something new happened. Things
didn’t just go back to the way they were; start over. Jesus did something new,
different. He rose from the grave and started a whole new day, an eighth day,
the day of eternity. The day of new creation. The day of forgiveness, life, and salvation.
That new day came for David when after confessing
his sin to Nathan, the prophet God
had sent him, he heard words of absolution; that God
was not going to strike him dead, but had put away his sin. And with that, the
great boulder of sin that had been crushing him had been removed. He could breath and live again. Yes, he could cover up his sin, but
he couldn’t get away from it. He needed something else. The
cleansing of God and the armor of God for his heart.
And you and me, too. Sometimes we do a pretty
good job at covering up and hiding our sin from others, but it’s still there,
isn’t it? It stick in our minds, it nags the
conscience, it drags us down, makes us afraid, and if left alone, in the end,
will crush us. We need the cleansing of God and the armor of God. We need
Jesus! Jesus to be crushed for our sin to atone for it so it doesn’t crush us,
Jesus to be raised to new life to break open the grave we fear, and Jesus to
speak to us those words of absolution to cleanse us from our sin and raise us
to a new life in Him.
But it’s not one and done. Our sins are like the
weeds in my garden - I pull them all but they keep coming back! And we keep
needing forgiveness so that the good plants and good fruits and good works
planted by Jesus can grow and flourish. The armor of God is for every day.
My baptism isn’t past tense but present tense. I AM baptized, that’s who I am.
And so I return to my baptism everyday,
and repent of how I have not lived as who I am. And the promises of baptism are
for everyday, the forgiveness of my
sins and the life of the Spirit. And the Gospel is for everyday,
the words of God through which the Spirit works in me. And the Body and Blood
of Jesus, though received once a week, nourish me all through the week. And
with these, the truth and righteousness and peace and faith and salvation and
Word and prayer of Jesus lives in me and I in Him. The whole armor and strength of God for me. Given by grace through faith.
So what are the Goliaths in your life? What sins,
what regrets, what challenges, what sorrows, what fears? And they’re big,
aren't they? And they’re strong, aren't they? And you want to be David, and go
up against them and win! But they’re big and strong and fearsome . . .
But remember how David did that. Remember what
armor he wore. It wasn’t his bravery, it wasn’t his strength, it wasn’t his
ability - it was his faith. His faith that God would fight
for him. His faith that God would win. It wasn’t
the little guy beats the big guy. It’s that God won. And He did -
not just with a headless giant, but with an open, empty tomb. That’s the
strength we need. That’s the armor we need. That cleanses sinful, fearful
hearts. That makes saints out of sinners. The armor of God.
For bodies and souls. For
life now, and for life forever.
In the Name of the
Father, and of the (+) Son, and of the Holy Spirit. Amen.
Now the peace of God which passes all understanding, keep your hearts and minds through faith in Christ Jesus, our Lord. Amen.
