How do we know the truths about sin and grace in the gospel are true?

The truths of Scripture, particularly concerning sin and grace, are validated by the person and work of Jesus Christ. Romans 10:4 declares that 'Christ is the end of the law for righteousness to everyone who believes.' This emphasizes the grace of God offered through Christ, who fulfilled the demands of the law and provided righteousness to all who are drawn to Him. Additionally, the transformative work of the Holy Spirit confirms these truths in the lives of believers, illustrating the power of the gospel to change hearts and draw people to faith. By presenting the gospel message, we are encouraged to trust in Christ's righteousness rather than our own efforts, highlighting the sovereignty of God's grace.
