Intro
In the accounts of Jesus’ crucifixion, we find that each Gospel writer mentions 
different facts about what took place on the cross.  Here’s how St. Mark 
describes Jesus’ death: “Jesus let out a loud cry and breathed His last” (Mark 
15:37).  But John and Matthew want you to know that Jesus “gave up His Spirit” 
(Matthew 27:50, John 19:30).  And when it came to a spear piercing Jesus’ side, 
only the Apostle John mentions that.  

But John also wants you to know what came out from Jesus after He was speared: 
blood and water.  He wrote: “When the soldiers came to Jesus and saw that he 
was already dead… one of the soldiers pierced his side with a spear, bringing a 
sudden flow of blood and water” (John 19:33-34).

Main Body
Jesus didn’t just stop breathing; He gave up His Spirit.  He didn’t just suffer 
and die; He released blood and water from His side.  For John, Jesus giving up 
His Spirit and pouring out blood and water have enormous significance.  

But how do we know that?  John tells us so, in His first epistle.  He wrote: 

Jesus Christ: He is the One, who came by water and blood.  He did not come by 
water only, but by water and blood.  And the Spirit is the One, who testifies, 
for the Spirit is the truth.  For there are three that testify: the Spirit, the 
water, and the blood; and the three are in agreement.

The Spirit, the water, and the blood came out of Jesus while nailed to the 
cross.  But that’s more than just historical fact; John says they are 
witnesses.  To be witnesses, to testify to us, means that they—the Spirit, the 
water, and the blood—have to come to us today.  If they don’t, how then can 
they testify to us, if they are not here to do so?  

And if “witness” or “testimony” wasn’t enough, John uses present-tense verbs in 
our epistle reading.  He wrote, “There are [not “were”] three that testify.”  
“Are”: That’s present tense.  Then he wrote, “If we accept human testimony, 
God’s testimony is [not “was”] greater, because it is God’s testimony.  “It 
is”: again, that’s present tense.  For the Spirit, the water, and the blood to 
testify to us in the present tense, means that they have to come to us today, 
bringing those events of Christ on the cross to us today.

So, what’s the Spirit?  John tells us.  In something that only he recorded in 
his Gospel, Jesus mentioned that Spirit in today’ Gospel reading.  Jesus, 
speaking to His Apostles, said, “As the Father has apostled me, so also am I 
sending you” (John 20:21).  Then Jesus breathed on them and said: “‘Receive the 
Holy Spirit.  If you forgive the sins of any, they are forgiven them; if you 
retain them, they are retained’” (John 20:23).

Jesus told His first pastors, His Apostles, to forgive sins (and if needed, to 
retain them) because He had given them the Holy Spirit for such a task.  And 
this Spirit testifies to us today, bringing Jesus’ forgiveness that He earned 
for us on the cross, through the spoken Word of His pastors.  The Spirit 
testifies to us, in the present tense, here and now, through such spoken 
forgiveness.  We Lutherans call that “absolution.”  

The Spirit speaks, giving what He says.  The men who speak are but the 
instruments: It’s the Holy Spirit who’s working and doing.  That’s John’s 
point: The Spirit testifies, bringing us Christ’s forgiveness from the cross, 
here today, in the present tense. 

But John also says the water testifies.  And John also tells us what that water 
is in something that only he recorded in his Gospel.  John tells us of Jesus 
speaking to Nicodemus, in John chapter 3.  Jesus said: “I assure you: Unless 
someone is born of water and Spirit, he cannot enter the kingdom of God” (John 
3:5).  Then, Jesus was pointing forward to the water of baptism.  But John, in 
his epistle, speaks of the water, of baptism, in the present tense.  It 
testifies to us now.

That’s what Paul says: “Don’t you know that all of us who were baptized into 
Christ Jesus were baptized into his death?” (Romans 6:3).  The water of baptism 
comes to us, here and now, in the present tense, giving what Jesus earned for 
us on the cross.  That’s why baptism can save, as the Apostle Peter writes (1 
Peter 3:21).  That’s why Paul calls baptism a “washing of rebirth and renewal 
by the Holy Spirit” (Titus 3:5).  

But John also says the blood testifies.  And John also tells us what that blood 
is in something that only he recorded in his Gospel.  John tells us of Jesus 
speaking to those whom He had earlier fed with fives loaves and two fish, in 
John chapter 6.  Jesus said, “I assure you: Unless you eat the flesh of the Son 
of Man and drink His blood, you have no life in you” (John 6:53).  In the same 
way that Jesus had pointed forward to baptism, He now pointed forward to His 
Supper.  But John, in his epistle, speaks of the blood, of the Lord’s Supper, 
in the present tense.  It testifies to us now.

That’s why the Apostle Paul wrote, “The cup of blessing that we bless, is it 
not a communion in the blood of Christ?” (1 Corinthians 10:16).  Yes!  In the 
Lord’s Supper, we take into our bodies the body and the blood of Jesus, where 
salvation for us on the cross becomes real in His real presence, here and now, 
in the present tense.  

This triple witness is true because, “it is the Spirit who testifies because 
the Spirit is [not “was”] the truth” (1 John 5:6).  Again, that’s in the 
present tense.  Because the Spirit is the truth, we believe the witness that 
comes to us in the Spirit, the water, and the blood, here and now, today, in 
the present tense (1 John 5:10). 

John says that those who believe in Christ have such faith within them (1 John 
5:10).  But here’s the kicker: such faith comes to us from outside of us!  
Without the testimony of the Spirit, the water, and the blood, we remain 
without God.  But the triple witness of the Spirit, the water, and the blood—of 
absolution, baptism, and the Lord’s Supper—come to us now, bringing us Jesus 
and His cross-won forgiveness and life.

John chapter 3, has the most well-known verse in the Bible: John 3:16.  “God 
loved the world in this way: He gave His only Son so that everyone who believes 
in Him will not perish but have eternal life.”  Jesus spoke those words, 
pointing forward to the salvation that He that would earn for all on the cross. 
 But Jesus spoke about believing in Him in the same conversation where He said 
that unless someone was born from above, by water and Spirit, by baptism, he 
would not be part of God’s kingdom.

Faith comes to someone through the ways that God chooses to give him faith.  We 
can’t produce that faith inside ourselves.  We can’t will it into being.  
That’s why Jesus spoke about believing in Him in the same conversation that He 
spoke about being born from above, by being spiritually born in the waters of 
holy baptism.  Jesus’ conversation connects belief in Him to an external means 
that brings such faith.   

God gives you eternal life; it’s not some wage that you earn.  Eternal life 
isn’t a carrot that God dangles in front of you, trying to get you to behave as 
if He were saying, “Do this and you’ll have eternal life.”  As John wrote in 
our epistle reading—God gives eternal life (1 John 5:11).  And God connects the 
life that He gives you in the belief, faith, and trust that He gives you.  
That’s what verse 10 of our epistle reading tells us: “The one who believes in 
the Son of God.”  

But then John goes on to say, “The one who believes in the Son of God has the 
testimony in himself.”  What is that testimony?  It’s what John had just 
mentioned: “There are three that testify: The Spirit, the water, and the 
blood.”  To have that testimony in you is to have Jesus in you through the ways 
He gives you forgiveness, life, and salvation: In absolution, the water of 
baptism, and the Lord’s Supper.  

Why does John connect belief to these witnesses, these testifiers, of God?  
It’s so we know that no one can create faith within himself.  But it’s also so 
we know where we receive the forgiveness, life, and salvation that Jesus earned 
for us on the cross.  It’s in the Spirit, the water, and the blood; in 
absolution, baptism, and the Lord’s Supper.

Did you catch John’s serious tone in our epistle reading?  He wrote, “The one 
who believes in the Son of God has this testimony within him.”  Okay, that 
triple testimony is Jesus coming to us in absolution, baptism, and the Lord’s 
Supper.  But then John says, “The one who does not believe God has made Him a 
liar.”  

So, how does unbelief make God a liar?  John goes on to tell us: Someone makes 
God “a liar because he has not believed in the testimony that God has given 
about His Son” (1 John 5:10).  This testimony isn’t some generic testimony 
floating in the air.  It isn’t just the truth that Jesus died for you on the 
cross.  It’s the triple testimony that John just mentioned: “the Spirit, the 
water, and the blood.” 

To say that Jesus’ cross-won forgiveness, and thus, salvation doesn’t come to 
you through the “Spirit, the water, and the blood” is to deny Jesus.  It’s the 
same as calling God a liar.  Jesus’ salvation for you comes to you in 
absolution, baptism, and the Lord’s Supper because those three witnesses 
connect you to the cross.  But if you don’t believe that Jesus’s salvation 
comes to you in such ways, then it does you no good.  Because as John says, 
it’s the same as calling God a liar.  

Conclusion
This triple testimony of the Spirit, the water, and the blood bring and keep 
you in the one, true faith.  That’s why you don’t have to wonder if you’re 
really saved or not.  You don’t have to hide your emotional turmoil, searching 
for such certainty within yourself.  God gives you external testimonies, three 
of them: the Spirit, the water, and the blood--absolution, baptism, and the 
Lord’s Supper.  

What a marvelous God we have!  He gives us, He gives you, external testimonies, 
so you know that you have forgiveness, life, and salvation.  So then, receive 
one such external testimony now: Christ as He gives you His saving body and 
blood.  Amen
