Trinity 1
Gen
15:1-6
6/22/25
Abraham was a pagan. There
is no other way to describe him. Joshua
told the people of Israel, “Thus says the LORD, the God of Israel, ‘Long
ago, your fathers lived beyond the Euphrates, Terah, the father of Abraham
and of Nahor; and they served other gods. Then I took your father Abraham
from beyond the River and led him through all the land of Canaan, and made
his offspring many.’”
Abraham, then known as Abram, and his father Terah had journeyed
from Ur in what is today southern Iraq. Their plan was to go to the land of
Canaan. But for some reason they had not
arrived there. Instead, they settled at Haran – a place that today is on the
border of Turkey and Syria.
Abraham did not know Yahweh. He worshipped the false gods of his
fathers. But Abraham had a special place in God’s plan of salvation. And so, in his grace, God called Abraham. We
learn in Genesis 12 that God said to Abraham, “Go from your country and
your kindred and your father's house to the land that I will show you. And I
will make of you a great nation, and I will bless you and make your name great,
so that you will be a blessing. I will bless those who bless you, and him who
dishonors you I will curse, and in you all the families of the earth shall
be blessed.”
God told Abraham to leave everything he knew. He promised to make Abraham into a great
nation. He promised that Abraham would be the means by which blessing would
come to all the families of the earth.
And then a little later, God promised to give the land of Canaan to his
offspring.
Abraham believed God’s promise. He trusted God. It was certainly a
great act of faith because everything about Abraham’s circumstances seemed to
contradict the promise. Abraham was seventy five years old. His wife Sarah was
sixty five. To expect that they would have a child at those ages was not
rational. But God had called Abraham, and he believed Yahweh’s word.
God had made his promise to Abraham. But time passed, and nothing
happened. Abraham and Sarah had no
child. Our text is introduced with the words “after these things.” These things were the events in the previous
chapter when Abraham had to lead a war party to rescue his nephew Lot from
local kings who had taken him captive. It was the kind of event that made a
person reflect on how fragile life was – and about the fact that Abraham had no
heir if he died.
We learn in our text that at this time God came to Abraham in a
vision and said, “Fear not, Abram, I am your shield; your reward shall be
very great.” Abraham obviously was
fearful about his future for he said, “O Lord GOD, what will you give me, for I
continue childless, and the heir of my house is Eliezer of Damascus?” And
then he added, “Behold, you have given me no offspring, and a member of my
household will be my heir.”
God had not given Abraham a child – he had no son. According to the
law of that time, a member of his broader household would be his heir. Yet Yahweh responded to him: “This man shall
not be your heir; your very own son shall be your heir.” Then he
brought Abraham outside and to him, “Look toward heaven, and number the
stars, if you are able to number them.” And he added, “So shall your
offspring be.” God reaffirmed his
promise, and stated it in an emphatic way. We learn that in response to this
Abraham believed the LORD, and God counted it to him as righteousness. He reckoned Abraham as having a righteous
standing before him.
In the first century A.D. Jews considered Abraham to be the great
example of a convert from the Gentiles.
He had not known God, and then God had called him. Later in chapter fifteen we learn about how God
made a covenant with Abraham in which he promised to give the land of Canaan to
Abraham’s offspring. Then in chapter
seventeen, he gave Abraham circumcision as the sign of the covenant, and
commanded that all of his offspring were to be circumcised.
The Jews pointed to Abraham’s faithfulness, for he had done
what God commanded. They said that
the Law of Moses was eternal, and that Abraham had kept the Law of Moses – the
Torah – in its unwritten form before it had even been given to Moses. Abraham
was the great example of doing the law.
After Paul had preached the Gospel of the death and resurrection of
Jesus Christ to the Galatians, other teachers arrived. They followed up on Paul’s work by saying
that, yes – a person needed to believe in Jesus. However, they said that in
addition to this the Gentile Galatians had to do what God’s people had always
done. They had to keep the Law of Moses.
It seems quite clear that they used Abraham as an example of this need. After
all, he had been circumcised, and now the Galatians needed to receive this as
well. These opponents held up Abraham’s faithfulness – his doing of God’s law –
in order to prompt the Galatians to keep the law of Moses.
Paul takes up Abraham as he addresses the Galatians. But he has a
very different emphasis. Instead of
Abraham’s faithfulness – his doing what God had commanded, Paul points to
Abraham’s faith – his belief and trust in God’s promise. The apostle
does so because faith and the law are mutually exclusive when it comes to our
standing before God.
The law is about works – about doing. Paul tells the Galatians, “But the law is not
of faith, rather “The one who does them shall live by them.” The law is about doing, and those who do that
law will be justified – they will be declared just by God. The apostles writes
to the Romans, “For it is not the hearers of the law who are righteous
before God, but the doers of the law who will be justified.”
The way of the law is clear and
unambiguous. But Paul warns that it can only lead to God’s judgment. The
problem is not the law, which in itself is holy and good as an expression of
God’s will. Instead, we the users of the law, are the problem. Paul tells the
Galatians that “the Scripture imprisoned everything under sin.” God’s Word
declares the truth about our status – we are fallen people who are under sin’s
power. Not only do we fail to do what we should. Even when we do it, the act is
not holy because our motives are never entirely pure.
That is why Paul says that “by works
of the law no one will be justified.” Instead, as we fail to do the law it
brings God’s curse. Paul writes, “For all who rely on works of the law
are under a curse; for it is written, ‘Cursed be everyone who does
not abide by all things written in the Book of the Law, and do them.’”
It is for this reason that Jesus
Christ gave himself for our sins. He, the Son of God, entered our world in the
incarnation in order to free us from the slavery of the curse. Paul told the
Galatians that, “Christ redeemed us from the curse of the law by becoming
a curse for us--for it is written, ‘Cursed is everyone who is
hanged on a tree.’” And then on the third day Christ rose from the dead as
he began the new life that is already at work in us through his Spirit.
Paul tells the Galatians, “we know
that a person is not justified by works of the law but through
faith in Jesus Christ, so we also have believed in Christ Jesus, in order to be
justified by faith in Christ and not by works of the law, because by works
of the law no one will be justified.”
It’s important to recognize that
Paul’s opponents at Galatia weren’t denying faith in Jesus’ death and
resurrection. They were saying that salvation takes place by faith in Jesus plus
doing the Law of Moses. In the
history of Christian theology, this is always the threat – the desire to add our
doing back into the cause of salvation.
We do this because we have been
created with the work of the law written on our hearts – we are hard wired in
our creation to understand the way of the law. We know that there is no such
thing as a free lunch – you get what you earn.
And deep down we also want to be able to claim some credit for having a
part in salvation.
This was the case in Martin Luther’s
day when God’s grace equipped the believer to take part in their salvation. It
remains the case in Roman Catholic theology today. But this is also what is
happening when people believe they are able by their own choice and power to
believe in Jesus. It is happening when living
a holy life becomes the final proof and assurance that a person is really
saved.
Paul points us to Abraham in rejection
of this. He cites the last verse of our text which says, “And he believed the
Lord, he counted it to him as righteousness” and then adds, “Know then that it
is those of faith who are the sons of Abraham.” Just as Abraham believed the promise that God
would give him an heir through whom all nations would be blessed, so we believe
in Jesus Christ the fulfillment of that promise.
The apostle goes on to say, “And the
Scripture, foreseeing that God would justify the Gentiles by faith,
preached the gospel beforehand to Abraham, saying, ‘In you shall all the
nations be blessed.’ So then, those who are of faith are blessed along with
Abraham, the man of faith.”
We believe in the promised seed of
Abraham – the promised offspring, Jesus Christ. By God’s grace, through faith
in Christ we are justified. Although we are sinful in ourselves, because of
Christ we know that God has already declared us righteous. He has done so, and he will do it on the Last
Day. We have been baptized into Christ,
and so we live as those who are in Christ.
We have been clothed with Christ in baptism and so we have the status of
being holy in God’s eyes.
Paul points to faith as the means by
which we receive justification before God.
He rejects the idea that our works have anything to do with it. But when
it comes to our life in Christ through the work of the Spirit he leaves no
doubt that faith is active and does.
He says in Galatians chapter 5, “For in Christ Jesus neither
circumcision nor uncircumcision counts for anything, but only faith
working through love.”
We have been freed by faith in
Christ. We have been freed from sin, and
from the law and its curse. But this freedom does not lead us inward as we
focus on ourselves. Paul says, “For you were called to freedom,
brothers. Only do not use your freedom as an opportunity for the flesh,
but through love serve one another. For the whole law is fulfilled in
one word: ‘You shall love your neighbor as yourself.’”
So as you live in Christ through the
work of the Spirit, act in love as you assist others. Don’t react in anger, but
instead be patient and self controlled. Be kind and gentle toward others,
treating them the way you want to be treated.
This morning we hear in our text: “And he believed the Lord, and he
counted it to him as righteousness.” Abraham believed and trusted in God’s
promise. In the same way, we believe and
trust in the fulfillment of God’s promise to Abraham – Jesus Christ. By God’s
grace through faith in Christ we are justified.
We know that it has been counted to us as righteousness, and that this
will be the verdict by God on the Last Day.
