Justification by Faith Alone: The Heart of the Gospel
The Apostle Paul, in his letters to the Romans and the Galatians, provides the most profound theological foundations for one of the core doctrines of Christianity: justification by faith alone in Jesus Christ alone. This doctrine is not a mere theological construct; it is the bedrock of Christian assurance and the wellspring of Christian joy.
Let’s explore this transformative truth as outlined in Romans 3:21-31 and Galatians 2:15-21.
The Righteousness of God Revealed
Romans 3:21-31 is a section of Scripture that marks a dramatic turn in Paul’s argument. After establishing the universal sinfulness of humanity, Paul unveils the righteousness of God apart from the law, which is attested by the Law and the Prophets. This righteousness is given through faith in Jesus Christ to all who believe. Herein lies the beauty of the gospel: it is not about human achievement but divine provision. Rather than trying to earn our salvation, God simply imputes (attributes or assigns) His very own righteousness to those who believe.
But now apart from the law the righteousness of God has been made known, to which the Law and the Prophets testify. This righteousness is given through faith in Jesus Christ to all who believe.
Romans 3:21-22
The Nature of God’s Mercy and Grace
God’s mercy is His compassionate response to our misery and sinfulness. It is not something we earn; it is given freely. His grace is the unmerited favor that not only forgives us but also bestows upon us the righteousness we need. In Christ, God’s mercy meets His justice as He justifies the ungodly (Romans 4:5).
However, to the one who does not work but trusts God who justifies the ungodly, their faith is credited as righteousness.
Romans 4:5
Justification by Faith: The Doctrine of Double Imputation
The doctrine of double imputation is central to understanding Paul’s message of justification. Our sin is imputed to Christ on the cross, where He bore the penalty we deserved. Simultaneously, His righteousness is imputed to us when we believe. This great exchange—our sin for His righteousness—is the heart of the gospel.
The controversy between “imputed” righteousness and the Roman Catholic doctrine of “infused” grace.
The controversy over the means of our justification (being declared righteous by God) came to a head during the protestant reformation. As a result, the institutional church split into basically two opposing and unreconcilable sides. The reformers believed that justification brings about sanctification, while the Roman Catholics taught that sanctification brings about justification.
Accordingly, the former view of the Protestants hold that our righteousness is not our own. It is God’s righteousness that He graciously credits (imputes) to us, in response to our faith in His Son. Whereas, the Catholics hold that it is our own actual righteousness, helped along (infused) by God’s grace, that determines our state of justification. The author believes that any reliance on self-righteousness, regardless of how it is aided, essentially nullifies God’s grace. Salvation comes from God alone, and He will not share His glory with another (Isaiah 42:8).
Christ’s Sacrifice and God’s Justice
God presented Christ as a propitiation by His blood, to be received by faith (Romans 3:25). Propitiation means that Christ’s sacrifice appeases the wrath of God and satisfies His justice. God can be both “just and the justifier of the one who has faith in Jesus” (Romans 3:26). He doesn’t simply overlook or pardon our sin. Rather, our sin is punished by the death of Jesus, and therefore God’s justice is upheld.
Freedom and Assurance in Justification
Liberation from Legalism
Galatians 2:15-21 confronts the legalism that threatened to enslave the believers. Paul asserts that “a person is not justified by works of the law but through faith in Jesus Christ” (Galatians 2:16). This declaration liberates us from the futile pursuit of trying to earn God’s favor through our efforts. It frees us from the yoke of the law and the tyranny of sin.
Assurance of Salvation
Justification by faith brings with it the assurance of salvation. Because our standing before God is based on Christ’s righteousness and not our own, we can be confident in our salvation. This assurance fuels our sanctification, as we “live by faith in the Son of God, who loved [us] and gave Himself for [us]” (Galatians 2:20).
The Transformative Power of Justification
Justification by faith alone in Christ alone is transformative. It changes our status before God—from guilty to being declared righteous, from alienated to becoming adopted. It also changes our hearts, as the Holy Spirit works within us, producing the fruit of the Spirit and conforming us to the image of Christ.
Living in Light of Justification
Understanding our justification should lead us to a life of humility and gratitude. For God has accomplished for sinners like us what we could not do for ourselves. Therefore, we are called to live in the freedom that Christ has secured for us, not using our freedom as an opportunity to sin, but through love serving one another (Galatians 5:13).
Conclusion: Embracing the Fullness of the Gospel
The doctrines outlined in Romans and Galatians are not mere doctrines; they are the essence of the Christian life. They are truths to be celebrated, lived out, and shared. Justification by faith alone in Jesus Christ alone is the doctrine upon which the Church stands or falls. It is the assurance that our sins are forgiven, that we are clothed in Christ’s righteousness, and that we have a sure hope of eternal life.
As we reflect on the richness of God’s mercy and grace, let us cling to the cross of Christ—the place where justice and mercy meet. Let us rejoice in the freedom and assurance that come from being justified by faith. And let us walk in the newness of life, empowered by the Spirit, to the glory of God the Father.
