How do we know that justification by grace is true?

Scripture consistently affirms that justification is an act of God's unmerited grace. In Titus 3:7, we see that we are justified by His grace and made heirs according to the hope of eternal life. This aligns with the larger biblical narrative that emphasizes faith in Christ as the sole basis for our standing before God. The transaction of justice and grace happens through the sacrificial work of Christ. Therefore, our justification rests not on our righteous deeds, but on God's abundant mercy seen in Jesus Christ, the author of our faith. This doctrine is foundational to the historic Reformed faith, ensuring that salvation is understood as a gracious gift from God.
