John Owen expounds on Romans 3:24-26, emphasizing that justification is solely by God's grace through faith in Christ's redemptive work, excluding any personal righteousness or works as a basis for justification. He argues that all have sinned and cannot achieve righteousness on their own, thus highlighting the necessity of Christ's sacrifice as the propitiation for sin. Owen asserts that boasting is excluded in the matter of justification, as it is entirely a work of grace, and concludes that faith alone is the means by which we receive this justification. He reinforces that the law is not made void through grace but is established through faith in Christ. Ultimately, Owen's message centers on the sufficiency of God's grace and the centrality of faith in the believer's justification.
