Link Romans 3:31 & Matthew 5:17-18?
How does Romans 3:31 connect with Jesus' teachings in Matthew 5:17-18?

Romans 3:31 in Context

“Do we, then, nullify the law by this faith? Certainly not! Instead, we uphold the law.”

• Paul has just declared that sinners are justified “apart from works of the Law” (Romans 3:28).

• Lest anyone think grace cancels God’s Law, Paul insists faith actually “upholds” it—keeps it standing, honors its authority.


Matthew 5:17-18 in Context

“Do not think that I have come to abolish the Law or the Prophets; I have not come to abolish them, but to fulfill them. For truly I tell you, until heaven and earth pass away, not a single jot, not a stroke of a pen, will disappear from the Law until everything is accomplished.”

• Jesus rejects any rumor that His mission is to scrap Scripture.

• “Fulfill” (Greek plēroō) means to fill up, bring to complete expression—never to discard.


Common Thread: Upholding and Fulfilling the Law

• Both passages answer the same objection: “If salvation is by faith in Christ, what happens to God’s Law?”

• Jesus: The Law continues until “everything is accomplished.”

• Paul: Faith does not “nullify” the Law; it “upholds” it.

• The Law’s moral demands stand; its ceremonial shadows reach their goal in Jesus (Colossians 2:16-17; Hebrews 10:1).


How Faith in Christ “Upholds” the Law

1. The Law’s penalty is satisfied in Jesus

• “Christ redeemed us from the curse of the law by becoming a curse for us” (Galatians 3:13).

• Justice is not relaxed; it is fully met (Isaiah 53:5-6).

2. The Law’s righteous requirement is fulfilled in believers

• “The righteous requirement of the Law might be fulfilled in us, who do not walk according to the flesh but according to the Spirit” (Romans 8:4).

• Through the indwelling Spirit, what the Law commands, grace empowers.

3. The Law is written on new hearts

• “I will put My law within them and write it on their hearts” (Jeremiah 31:33).

• Faith unites us to the New Covenant where obedience flows from inside-out transformation, not external compulsion.

4. The Law’s tutor role leads to Christ

• “The Law has become our guardian to lead us to Christ, that we might be justified by faith” (Galatians 3:24).

• Faith confirms the Law’s purpose by taking us to the very Savior it points toward.


Practical Implications for Today

• Relish God’s Law as a faithful revelation of His character—never a ladder for earning salvation.

• Depend on the Spirit to live out the Law’s moral core: love for God and neighbor (Matthew 22:37-40; Romans 13:8-10).

• Honor the whole counsel of Scripture—Genesis to Revelation—as trustworthy and enduring.

• Proclaim a gospel that magnifies both grace and holiness: Christ forgives and transforms.
