What Does It Mean to Be Justified by Faith? Lessons from Romans 4 and the Life of Abraham

From a message by Jon Alsdorf 
Faith has always been at the center of God's plan for humanity. Not works, not heritage, not effort. Just faith. Romans chapter 4 makes this clear through the life of Abraham, and the implications are just as relevant today as they were when Paul first wrote them.

Why the Book of Romans Matters (And How to Read It)
Romans can feel overwhelming. It is long, layered, and packed with theological concepts. But everything in the book flows from one central thesis found in Romans 1:16-17.

"For I am not ashamed of the gospel, for it is the power of God for salvation to everyone who believes, to the Jew first and also to the Greek. For in it the righteousness of God is revealed from faith for faith, as it is written, 'The righteous shall live by faith.'" - Romans 1:16-17

That one phrase, "the righteous shall live by faith," is the thread that holds the entire book together. Paul spends the rest of Romans answering one core question: who is righteous, and how does that righteousness come?

Why You Cannot Ignore the Old Testament
Before diving into Romans 4, it is worth addressing something that trips a lot of people up. Some teachers and writers suggest the Old Testament is something Christians can safely set aside. That is a serious mistake.

The Old Testament and New Testament are inseparable. Everything introduced in the Old Testament is fulfilled and revealed in the New. Everything found in the New Testament is hidden in the Old. When you embrace both together, the full picture of God's plan comes into focus.

There Is No Room for Personal Pride at the Cross
Romans 4 opens with Paul using Abraham as an illustration of what it means to be justified by faith. His first point cuts straight to the heart.

"For if Abraham was justified by works, he has something to boast about, but not before God. For what does the Scripture say? 'Abraham believed God, and it was counted to Him as righteousness.'" - Romans 4:2-3

If Abraham had earned his righteousness through good deeds, he would have reason to boast. But he did not earn it. He believed God, and that belief was credited to Him as righteousness.

Personal pride is one of the biggest barriers to receiving salvation. The desire to earn it, to contribute something, to pull yourself up spiritually by your own effort, is rooted in pride. And that pride will keep you stuck.

Many people spend years frustrated in their faith because they are working hard to accomplish something that only Jesus can accomplish. The turning point comes when a person finally stops striving and simply receives what Christ has already done.

Repentance is not just turning away from individual sins. At its core, it is turning away from the arrogance that says, "I can help earn this." Salvation is not a partnership between you and Jesus. It is Jesus alone.

What the Story of Abraham Actually Teaches Us About Faith
The moment Paul is pointing to in Genesis 15 is not the dramatic scene where Abraham prepares to sacrifice Isaac. It is much earlier, and much more ordinary.

Abraham was an old man. His wife was old. They had no children. God had promised to make Him the Father of many nations, and Abraham had no idea how that could possibly happen. God did not explain the how. He simply said it would be so.

And Abraham believed Him.

That was it. No great act of heroism. No perfect track record. Abraham was a man who had made plenty of mistakes, who had tried to take matters into his own hands more than once. But in that moment, he trusted God with something that seemed impossible.

God counted that faith as righteousness.

This is the accounting language Paul uses. God reconciled the books in Abraham's favor, not because of what Abraham had done, but because of what Abraham believed.

David Understood This Too
Paul also brings in David to reinforce the point. He quotes from Psalm 32:

"Blessed are those whose lawless deeds are forgiven, and whose sins are covered. Blessed is the man against whom the Lord will not count His sin." - Psalm 32:1-2 (quoted in Romans 4:6-8)

David knew this truth personally. His life was marked by failure, scandal, and consequence. Yet his trust in God never wavered, and He understood the depth of God's grace and forgiveness. Righteousness was never about David's perfection. It was about God's mercy received through faith.

Salvation Is for Everyone Who Believes, Jew and Gentile Alike
One of the most radical claims Paul makes in Romans 4 is that salvation has never been limited to one group of people.

He points out that Abraham received circumcision as a sign of the righteousness he already had by faith. The sign came after the faith. That means circumcision was never the source of his justification. It was a symbol of something that had already happened.

"The purpose was to make him the Father of all who believe without being circumcised, so that righteousness would be counted to them as well." - Romans 4:11

This was a ground-shaking statement in the first century. Many Jewish believers struggled with the idea that Gentiles could be fully included in God's family without adopting Jewish practices. Paul makes it clear: there is not one version of salvation for Jews and another for Gentiles. There is one gospel, one faith, and one way of being made right with God.

The same is true today. Salvation is not reserved for a particular background, heritage, or religious tradition. It is for all who believe.

All Believers Are Children of Abraham Through Faith
Building on this, Paul makes another bold claim. All who believe are spiritually connected to Abraham.

"That is why it depends on faith, in order that the promise may rest on grace and be guaranteed to all his offspring, not only to the adherent of the law but also to the one who shares the faith of Abraham, who is the Father of us all." - Romans 4:16

God told Abraham He would make Him the Father of many nations. Paul says this was never just about physical descendants. It was about every person from every nation who would follow in Abraham's footsteps of faith.

When someone from any background, any language, any culture places their faith in God, they are walking the same path Abraham walked. That makes Abraham a spiritual Father to all who believe.

You Are Declared Righteous by Divine Decree
Paul closes the chapter by making the personal application clear.

"But the words 'it was counted to him' were not written for his sake alone, but for ours also. It will be counted to us who believe in him who raised from the dead Jesus our Lord, who was delivered up for our trespasses and raised for our justification." - Romans 4:23-25

The story of Abraham was written for us. The same faith that was credited to Abraham as righteousness is credited to everyone who believes in Jesus. Jesus took our sin to the cross and rose again so that we could be declared righteous, not because of anything we did, but because of everything He did.

The Hidden Story of Salvation in Abraham's Life
There is one more layer worth noting. In the story of Abraham preparing to sacrifice Isaac, a remarkable picture of the Trinity appears.

Abraham represents God the Father. Isaac represents the Son. And the unnamed servant who accompanies them, identified earlier in Genesis 15 as Eleazar, represents the Holy Spirit. The name Eleazar means "God is my helper," and can also be translated as "God is my comforter." The Holy Spirit is called the Comforter in the New Testament.

In the story, the Father and Son tell the servant to wait while they go ahead. Later, the Father sends the servant out to find a bride for His son, and the servant qualifies her by offering gifts and inviting her to choose for herself.

The New Testament is hidden in the Old Testament. God's plan of salvation is woven through the life of one man, across decades, pointing forward to Jesus.

Life Application
This week, take an honest look at where pride might be getting in the way of your faith. Are you still trying to earn something that has already been freely given? Are you frustrated in your spiritual life because you are working hard to accomplish what only Jesus can accomplish?

The challenge this week is simple but not easy: surrender the effort. Stop trying to help Jesus save you, and simply receive what He has already done.

Ask yourself these questions:

• Am I trusting in Jesus alone for my righteousness, or am I still trying to contribute something to my own salvation?
• Where in my life am I striving out of pride rather than walking in faith?
• Have I truly repented of self-reliance and received the gift of salvation on God's terms, not my own?

Righteousness has always come by faith. It came that way for Abraham. It came that way for David. And it comes that way for you. The question is whether you are willing to let go of your own effort and trust Him completely.
