What is the relationship between God's Word and justification?

Justification, the act of being declared righteous in God's sight, is entirely centered on faith in Jesus Christ, as articulated in Romans 5:1, which states that we are justified by faith and have peace with God through Jesus. This concept emphasizes that our justification is not based on our own works but on the righteousness of Christ imputed to us. God’s Word assures us of our justification, and rejecting this promise equates to calling God a liar. Thus, understanding and believing in the promises of Scripture concerning justification is foundational to our faith and assurance of salvation.
