“The Depths of the Sea”
Text:
Romans 11:33-12:8; Matthew 16:13-20; Isaiah 51:1-6
Grace, mercy, and peace to you from God our Father,
and from our Lord and Saviour Jesus Christ. Amen.
One of the more amazing things science has done
lately is send unmanned vehicles down into the depths of the sea. Deeper than
we’ve ever been before and maybe deeper than we even knew the sea to be! And
those probes have sent back pictures of things never before seen - weird and
unusual creatures. Things no one could imagine or even think real, had we not
seen the images.
But there is something even deeper and more
amazing, unsearchable, and inscrutable than that. We heard it from St. Paul
today. He said, Oh, the depth of the riches and wisdom and
knowledge of God! How unsearchable are his judgments and how inscrutable his
ways! So if we could plunge the depths of God’s mind, the depths
of God’s wisdom and knowledge, what we would discover? Things unimaginable, I’m
sure! Things beyond our wildest imagination. Things perhaps, to us, weird and
unusual.
Things like . . . using the horrific death of the
cross to save. Using suffering to help us. Using the devil and evil for good.
Using water to wash our hearts and bread and wine to feed our souls. Things no
one could imagine and even think real - not because we have seen
these things (Iike with the ocean), but because we
have been told them. Because they have been revealed to us by God
Himself.
A device that lets you see underwater and reveals
that world is called a bathyscope. What
reveals to us the depth of the riches and wisdom and knowledge of God
and reveals to us His mind is His Word.
So when Jesus asked His disciples, Who do
people say that the Son of Man is? and Peter responded for them all, You
are the Christ, the Son of the living God, Jesus called Peter blessed -
not blessed because of the answer he gave, but blessed in
order to give the answer he gave. Because this had been revealed to
him and the others. Revealed by the Father in the Scriptures that
Jesus was teaching and fulfilling. Otherwise, making the connection of this guy
Jesus from Nazareth and the very Son of God would never have entered their
minds. Just like those weird and unusual creatures in the depth of the sea we
could never have imagined, were they not revealed to us.
This is the rock, the rock of God’s Word, of God
revealing this truth to us and our confessing this truth, the rock of the
forgiveness of sins - the forgiveness
that Peter and the others are then told to go give just as they have received
- this is the rock upon which the Church is built. The rock on which it can
never be moved. Not even by the gates of hell - no matter how
close, dark, and fearsomely looming they may be.
And sometimes they seem pretty close, don’t they!
And fearsome. And seem to be winning. We see the evil in the world and the evil
in our lives and the sin and wickedness that sometimes spews from us, and that
rock on which the Church is built can seem like a little pebble that ain’t much!
So this is where we need the bathyscope
of God’s Word - so that we can see below the surface, below just what we can
see happening in the world to the depths of God’s wisdom and knowledge and
work. Because there’s stuff going on beneath the surface that we could never
imagine and would never think true were it not revealed to us.
And one of those Scriptures revealing this to us is
the Old Testament reading we heard today from Isaiah, who tells us to look
to Abraham and Sarah. God says, he was but one when I called him,
so that I might bless him and multiply him. And we know
how God did that, but don’t forget how He did that through a lot of
hardship, pain, difficulties, and ways Abraham could never have imagined! (And
frankly, didn’t want!) Like, when God told him to sacrifice his son Isaac as a
burnt offering. Unimaginable! Inscrutable! Right?And
yet, God blessed. And then the stories of what happened to Jacob and Joseph and
David . . . the Word of God revealing to us the depths of the riches and
wisdom and knowledge of God. Showing us that, as Paul went on to say,
that from him and through him and to him are all things. ALL
things. Things that seem to us good and things that seem to us evil.
There is nothing that is not from Him, nothing that is not used
by Him, and nothing that is not for Him. To His glory forever.
AMEN!
Now wait a second, Pastor! ALL things? Even evil
things? How can that be? God isn’t evil or cause evil! True. But He can
and does use it for good. And imagine how frustrating that must
be for the devil! When God turns around his evil and wicked ways for His own
good! Like, when the devil tempts us into sin, and then drives us to despair
because of that sin, but God then turns that and uses that to drive us to
confess our sins and find refuge and hope in Jesus! Or when evil drives us to
prayer, confusion drives us to the Word, our hunger and thirst for something
better drives us to the altar. And like Abraham, God blesses us through such
hardship, pain, and difficulty . . . which we frankly don’t want! But
God knows that we need. Not to punish us, but in order to bless us.
And, of course, the example par excellance of God using evil for good is His own cross.
The cross on which He - the Son of God, God Himself - hung. The hatred and evil
of men putting Him there, but then every drop of blood from His head, His
hands, His feet, His back, and His side, providing life and forgiveness and
blessing. And then His resurrection breaking open death and the grave - a depth
even greater and more foreboding than the depths of the sea - but conquered by
Jesus for you. So that, as one of our hymns says (LSB #883 v.3), we can fear the grave
as little as our bed.
Those probes that have revealed to us the depths of
the sea - and other discoveries of science - have caused us to rethink what we
thought we knew. And so it is also with God’s Word. When the depths of
the riches and wisdom and knowledge of God are revealed to us, our
hearts and minds and lives are transformed. It’s not just that we
rethink what we thought we knew (although we do), but that the Spirit of God transforms
us. That’s the word Paul used today. And it is the same word used of Jesus in
His transfiguration! That’s how God wants to bless and transform us! From this
to that. From cross to glory. From the earthly to the eternal. And it is
His Word and Sacraments that do that. That both reveal that to us and work
that in us.
For, as God said through the prophet Isaiah, my
righteousness draws near, my salvation has gone out, and my arms will judge the
peoples. Now it’s hard, perhaps, to wrap your mind around that, because
the world we live in doesn’t seem to have righteousness anywhere near! And
because righteousness and salvation are abstract things. But God’s Word then
plumbs the depths of that for us and reveals to us what He means and makes it
concrete for us. That these words of Isaiah are talking about Jesus. That He
is the righteous one who drew near us. That He is the saving one
who has come down from heaven to us. And that His arms took the
judgment of God against the sin of the world on the cross. Bringing a salvation
and a righteousness that will be forever because His resurrection
is forever.
And when that is yours, when you can fear the
grave as little as your bed, when you know your life and future are secure
in Jesus, when you are baptized by His hand and fed with His Body and Blood,
because Jesus offered His body as a dead sacrifice (though now risen!), you
can now, as Paul said, present your bodies as a living sacrifice.
You can entrust your life to Him. And not in an abstract way - but just as the
righteousness and salvation of God came down in a concrete way in Jesus, so you
entrust your life to God in concrete ways as well. Husbands laying down your
life for your wife. Wives honoring and respecting your husband. Children
honoring, serving, obeying, loving, and cherishing your parents. By forgiving
as you have been forgiven. By serving, giving, encouraging. Not that any of
that will now be easy! I don’t know if it ever will be! But knowing the
depths of the riches and wisdom and knowledge of God, of all that He
has done for you and has promised you, of His Word transforming your heart and
mind and life . . . you now can. And you know that though hard,
God is using it to bless - both you and those you serve.
And even though the gates of hell might seem like
they are your next door neighbor, or even in your own home, they cannot win.
They cannot put Jesus back in the grave or back on the cross or send Him back
into heaven. He is here for you. And He’s not leaving. He’s going to
keep washing you and feeding you and lifting you up and through His Word
revealing to you the depths of His love for you. Love that is beyond what you
could imagine or ever think real. Yet there it is. On the cross, in the font,
and on the altar for you. Weird and unusual . . . maybe. But life changing
and life giving.
So now I’m going to ask our organist to play hymn
#611 during the offering after the prayers, and as she does, I want you to read
along. It kind of sums up what I’ve said here today. And maybe during those
tough times in your life - those Abraham times! - it can remind you of the
depth of God love for you that is deeper than the depths of the sea, and
lasting to eternity. The love that found you, the love revealed to you, the
love that you confess, and the love that saves you.
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.
