The doctrine of justification by faith alone means that God declares a guilty sinner to be righteous only on the basis of faith in Jesus Christ. This faith is not a work; it is an empty hand that receives Christ’s righteousness. Good works follow justification but contribute nothing to it.
1. All Have Sinned and Cannot Be Justified by Works of the Law
Every human being has sinned and fallen short of God’s glory. Therefore, no flesh can be justified by the works of the law, because the law only brings knowledge of sin. The law demands perfect, perpetual, personal obedience, which no sinner can provide.
2. God’s Righteousness Is Revealed Apart from the Law
God has revealed a righteousness that does not come from keeping the law. This righteousness is from God and is given through faith in Jesus Christ. It is available to all who believe, without distinction.
3. Justification Is a Gift of Grace, Not a Wage
Justification is not payment for work done. It is a free gift of God’s grace. If it were by works, it would be a debt owed, not grace. But God justifies the ungodly freely.
4. Christ’s Blood and Resurrection Are the Ground of Justification
God justifies sinners because Christ’s blood was shed for their sins and He was raised for their justification. Christ’s obedience unto death is the sole legal basis upon which God can declare the guilty righteous. God is both just and the justifier of the one who has faith in Jesus.
5. Faith Is Counted as Righteousness
Abraham believed God, and it was counted to him as righteousness. This was not because faith is a meritorious work, but because faith receives the promise of God. To the one who does not work but believes on Him who justifies the ungodly, faith is counted for righteousness.
6. Works Do Not Justify; They Evidence Justification
A man is justified by faith without the deeds of the law. Works have no role in the declaration of righteousness before God. However, true faith is never alone; it produces good works as its fruit. But these works justify the believer before men, not before God.
7. Boasting Is Excluded
Because justification is by grace through faith alone, boasting is completely excluded. No one may boast of their works, their obedience, or their moral effort. All glory belongs to God alone.
Conclusion
Justification by faith alone means that the sinner is declared righteous before God solely on the basis of Christ’s finished work, received through faith alone. This doctrine is the article upon which the church stands or falls. Good works are the necessary evidence of justification, never its cause.
