In the 16th century, Martin Luther described Romans 3:21-26 as the most important paragraph in the Bible. Why would that have been the case? Luther recognized that this paragraph holds crucial Christian truths that are glorious and life-changing. Let’s look first at Romans 3:21.
For example, Romans 3:21 begins with “But now.” This is important because Romans 1:18-3:20 made the case that everyone (Jew and Gentile) is condemned for sin. “But now” God has done something amazing, something that brought hope into a hopeless situation. God has “made known” his “righteousness” (3:21). I believe this refers to His saving righteousness. There is a way to be right with God “apart from the law.” Being right with God does not result from law-keeping.
Finally, consider the words “to which the Law and the Prophets testify.” What God did in Christ is in fulfillment of what God promised in the Old Testament. According to God’s plan and timing, the Word became flesh (John 1:14) and was born into this world (Galatians 4:4). Through Christ’s crucifixion and resurrection, God revealed His saving righteousness.
