Matthew 5:18's role in Scripture's authority?
How does Matthew 5:18 affirm the authority of Scripture in our lives?

Setting the Scene

Matthew 5:18: “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.”


What Jesus Declares about Scripture

• “Truly I tell you” – a solemn oath underscoring absolute certainty.

• “Until heaven and earth pass away” – the longest conceivable span; Scripture outlasts creation itself.

• “Not a single jot, not a stroke of a pen” – even the smallest Hebrew marks are preserved.

• “Until everything is accomplished” – every prophecy, promise, and command will reach its fulfillment.


Permanence and Reliability

Psalm 119:89 – “Your word, O LORD, stands firm in the heavens.”

Isaiah 40:8 – “The word of our God stands forever.”

1 Peter 1:25 – “The word of the Lord endures forever.”

Together with Matthew 5:18, these passages reveal Scripture’s immovable stability.


Total Inspiration

2 Timothy 3:16-17 – “All Scripture is God-breathed…”

John 10:35 – “Scripture cannot be broken.”

Jesus’ reference to every jot and tittle echoes the Spirit-breathed precision of every word.


Completeness and Fulfillment

Luke 24:44 – Jesus said that everything written “must be fulfilled.”

Revelation 22:18-19 – warnings against adding or subtracting words highlight a closed, complete canon.

Matthew 5:18 anticipates the day when all Scripture meets its goal in Christ’s return and the new creation.


Practical Authority in Daily Life

Because every detail is preserved and purposeful:

1. Obedience is non-negotiable—no command is outdated (James 1:22).

2. Doctrine is secure—truth does not shift with culture (Ephesians 4:14).

3. Assurance is strengthened—promises cannot fail (Hebrews 10:23).

4. Moral boundaries remain firm—God’s standards do not erode (Psalm 119:9).

5. Hope is anchored—prophecies will be accomplished (2 Peter 1:19).


Living Under Scripture’s Authority

• Study it diligently (Acts 17:11).

• Submit thoughts and decisions to its counsel (Psalm 119:105).

• Teach it faithfully, without alteration (Titus 2:1).

• Trust its promises and warnings equally (Romans 15:4).

Jesus’ word in Matthew 5:18 settles the question: Scripture stands unaltered, unbreakable, and utterly authoritative for every aspect of life.
