The text for today is our Gospel
lesson, Luke 13:22-30.
Grace and peace to you from God our
Father and the Lord Jesus Christ!
It’s a common question, one often
discussed by Jewish teachers during the day of Jesus’ ministry and the focus of
speculation in our own day: “Lord, will those who are saved be few?” Some of the rabbis taught that all Israelites
would have a share in the world to come; others, that only the spiritually
elite (like them) would make the cut. Jesus’
answer is quite different, a sobering warning that should cause everyone to
think—especially us who consider ourselves Christians.
You see, once again people are
asking the wrong question. And they are
concerned about the wrong person.
“Instead of being so concerned about an abstract ‘How many?’ Jesus says,
“You strive to get in.” Instead of wondering about others, check yourself. Will you
be saved? Will you enter the kingdom
of God? Will you
recline at table with Abraham, Isaac, Jacob, and all the prophets? Or will you
will be cast out and left on the outside where there is weeping and gnashing of
teeth? Will you hear those dreadful words: “I tell you I do not know where you
come from. Depart from Me, all you
workers of evil”?
Theoretical questions, framed in the
third person, put off repentance and do not lead to saving faith. So Jesus will not let us examine others
without first examining ourselves. It’s
a sobering truth: Some people are going to be rejected from the kingdom just as
they have rejected the King. “Strive to
enter through the narrow door. For many,
I tell you, will seek to enter and will not be able.”
Several of Jesus’ kingdom parables
compare salvation to a great feast, or a banquet, given by a king. That is also the picture He uses here. Entrance into the banquet hall is by a single
door. Notice, it’s a narrow door. That prevents great crowds of people from
entering all at once.
I picture the corral and narrow
chute that we would use for counting sheep or vaccinating cattle. You might think of a queue line at a fair with
the turnstile that only allows you to enter one at a time. That is the point that Jesus is trying to
make. Entrance into the banquet is
gained by going through the door one at a time.
There is no group admission. It
doesn’t matter if you were born of the Israelites, or if you’ve come from a
long line of church-going Christians.
Entrance into the banquet is gained by going through the door one at a
time. And that door is Jesus
Himself. One enters the banquet hall by
way of Jesus, the Lord of the Banquet.
Jesus urges His hearers: “Strive to
enter through the narrow door.” Now
Jesus isn’t saying that you earn your way into heaven. Indeed, He was on His way to complete that
task for you. What He is saying is that
once saving faith is created in your heart, you are engaged in a terrible
struggle to keep it. You must guard
against everything that threatens to destroy it. And to show how difficult it is, the Greek
word translated “struggle” or “strive” is the word from which we get the word
“agony.” And indeed, such a struggle is
agony. It’s hard and it’s constant. And what do you agonize over? Well, certainly your sinful condition and the
fact that you fall short of God’s glory.
Old Adam constantly wages war on your new nature, enticing you to follow
the desires of your sinful heart.
So, do you agonize over that? Do you know the agony of fighting against your
sin? Or have you become comfortable with
your sin, doing whatever you want without fearing God’s wrath? Do you give in to sin too easily thinking it
is okay because God will forgive you anyway?
Dear friends, this should not
be! As God’s beloved children you must
strive against your sin with every ounce of strength. And to show the extent to which that struggle
goes, consider today’s Epistle: “In your struggle against sin you have not yet
resisted to the point of shedding your blood” (Hebrews 12:4). No, you haven’t blood. Not one pint.
Not one drop. Yet such struggle
must be your aim.
And if that weren’t bad enough,
Satan will do whatever he can to destroy your faith. And that makes the struggle doubly
tough. You can’t “see” the devil; but you
still have to fight against him. And
that struggle doesn’t end until you rest in peace—in Christ. You agonize over sin and temptation, the
devil, the world, and your own sinful flesh, until you are laid to rest in the
grave where you will lie until the resurrection of all flesh.
Now, of course, you do not strive or
struggle alone. For you have One who has resisted sin to the point of
shedding His blood. Our Lord Jesus went
to the cross and suffered the ultimate agony over sin—for you. For you, He shed His holy, precious
blood. For you and your sin, Christ
suffered God’s fiery wrath. For you,
Jesus not only endured pain, humiliation, and thirst, but suffered the torments
of hell. For you, Jesus gave up His
spirit, that He might give you His Holy Spirit.
He did all of this that you might believe His Word and receive His
forgiveness, so that you might live as His dear child now and dwell with Him
forever.
The struggle through which one
enters the kingdom
of God is repentance,
which is actually a work of God in the human heart. The struggle is produced when the Word of
God—such as the teaching of Jesus here—calls you to repent and trust in Christ,
but your sinful nature rebels against God’s Word. The struggle is only resolved if you give up
or your old Adam is put to death by the Law and you are raised to new life with
Christ by the power of the Gospel.
St.
Paul offers a window into this inner struggle in Romans 8:13: “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.”
This ongoing, lifelong struggle characterizes the lives of all who are
baptized into Christ. In the Small
Catechism, Luther describes the baptismal life: “The Old Adam in us should by
daily contrition and repentance be drowned and die with all sins and evil
desires, and that a new man should daily emerge and arise to live before God in
righteousness and purity forever.”
So, how do you enter the narrow
door? Only through Jesus, of
course. By God’s grace and power, repent
of your sins, confess them, receive Christ’s forgiveness, and believe His
promises of eternal life. Just like you
did at the beginning of the service.
Remember?
You confessed to almighty God,
merciful Father: “I, a poor miserable sinner, confess unto You all my sins and
iniquities with which I have ever offended You and justly deserved Your
temporal and eternal punishment. But I
am heartily sorry for them and sincerely repent of them, and I pray You of Your
boundless mercy and for the sake of the holy, innocent, bitter sufferings and
death of Your beloved Son, Jesus Christ, to be gracious to me, a poor, sinful
being.”
And Jesus spoke to you through His
called and ordained servant: “I forgive you all of your sins in the name of the
Father and of the Son and of the Holy Spirit.”
That is the essence of the struggle.
That is how you strive to get through the narrow door. It’s actually quite simple; but it’s never
easy!
You can’t enter on the strength of
your own efforts; rather, you enter only in the arms of Jesus as He carries you
in. Thus, your striving to enter the
kingdom is to receive Jesus and all that He has done for you even as you strive
against the sins which would entice you away from Him. Entrance through the narrow door is gained by
those who repent and see in Jesus the Lord of the Banquet, for this door opens
up into the house in which the end-time feast is to be celebrated.
Notice the
sense of urgency. Time is of the
essence. The time will come when the Lord
is going to close that door. There will
be some who will come knocking on the locked door demanding entry, but He will
not open. Just as the time will come
when the individual tree will be cut down, so also the time will come in each
individual’s life and in the history of the world when the entrance to
salvation will be closed. The message is
plain: Don’t delay, but strive to enter now before it is too late. “For many, I tell you, will seek to enter and
will not be able.”
So heed
this warning: Not everyone will make it into the kingdom of God! It is a narrow, difficult way. But you need not despair, nor should you exhaust
yourself futilely struggling to get through the door by your own efforts. Those who enter the kingdom of God
pass through the door by grace, and the examples from the New Testament encourage
as well as instruct.
One of
the clearest examples of this is found in Acts.
After Peter’s sermon on Pentecost the crowd asks a similar question to
the one posed in our text, but there is an important difference. Convicted of their sins, they ask it in the
first person: “What should we
do?” The answer given is that Baptism in
the name of Jesus—a Baptism of repentance to the forgiveness of sins with the
gift of the promised Spirit—provides all that is necessary for entrance (Acts
2:37-39).
St.
Luke goes on to tell us those that were baptized were added to the number of
those being saved. They also remained
steadfast “in the apostles’ doctrine, in the fellowship, in the breaking of the
bread, and in the prayers” (Acts 2:42).
In other words, they remained in Christ’s Word—His Word and
Sacrament. They joined with their fellow
believers in worship and the Lord’s Supper, thus anticipating and rehearsing each
Lord’s Day for the unending, end-time feast.
And so
Jesus ends His discourse on the kingdom
of God with a description
of the people sitting at the banquet tables.
As is to be expected, Abraham, Isaac, Jacob, and the prophets are
there. But then comes a surprise: many
of Jesus’ contemporaries will find themselves on the outside looking in. Those who considered themselves to be among
God’s people, the religious elite, will not gain entrance. They will see that other people from all over
the world will be sitting in their places at the banquet of salvation. Those who first had the opportunity to
respond to Christ’s preaching will find themselves left out; those at the very
ends of the earth who heard the Gospel message last will find themselves
honored with choice seating at the heavenly banquet
Now, in
the upside-down, inside-out, topsy-turvy way of the Gospel, both those in
heaven and those left out will be surprised.
Many of those on the outside will say, “I don’t deserve this.” But of course they do, because they refused
the gift of life when it was offered to them or they gave up in their struggle
against sin and entering the narrow door.
Perhaps they even looked for another way in, relying on their religious
heritage, good works, or a passing knowledge of Jesus.
Those
on the inside will also say, “I don’t deserve this.” And they are absolutely correct. They don’t deserve it. By God’s grace in Jesus’ death on the cross,
all the sins of the world were atoned for.
By God’s grace and as a free gift, He created saving faith in you. And it’s that faith that will get you through
the narrow door, for it clings only to Jesus and His forgiveness.
That’s
why it’s so important to guard your gift of faith. That’s why it’s important to be diligent and
faithful in attending the services of God’s House. For in the Absolution, the preaching of the
Gospel, the partaking of the Lord’s Supper, you receive forgiveness, salvation,
and eternal life in the kingdom
of God. In these means of grace your faith is
strengthened and you are empowered to continue in your struggle against sin.
“Lord, are only a few going to be
saved?” asks the man in our text. But
Jesus doesn’t answer his question—at least not with a yes, a no, or a
number. As He often does He directs His
students to what is really important, what really matters, what has eternal
consequences. Jesus warns that the door
is narrow, so that you strive to remain faithful to His Word. But, He also has Good News for you: His grace
is sufficient and the door is wide enough to gather people from all nations,
from the four corners of the earth, into His kingdom.
And you, dear Christians, are among
those gathered. Of this you can be sure,
for you are forgiven for all of your sins in the name of the Father and of the
Son and of the Holy Spirit. Amen.
