1 Sam 15:29 & Heb 13:8: God's unchanging nature.
Connect 1 Samuel 15:29 with Hebrews 13:8 about God's consistency.

Setting the Stage

• The Old Testament prophet Samuel and the New Testament writer to the Hebrews speak centuries apart, yet both highlight the very same truth: God never changes.

• Their words give us an anchor in a world that keeps shifting under our feet.


God’s Unchanging Character in 1 Samuel 15:29

“Moreover, the Glory of Israel does not lie or change His mind; for He is not a man, that He should change His mind.”

• “Glory of Israel” is a title for the Lord, underscoring His majesty and covenant faithfulness.

• Samuel contrasts God with humanity—people are fickle, God is not.

• “Does not lie” and “does not…change” form a double assurance: His words and His will remain steady.

• Context: Even while announcing judgment on King Saul, God’s own character stays perfect and constant. His justice and mercy never wobble.


Jesus’ Timeless Consistency in Hebrews 13:8

“Jesus Christ is the same yesterday and today and forever.”

• The verb “is” in present tense links all three time frames—past, present, future—into one seamless identity.

• By applying immutability language to Jesus, the writer affirms Christ’s deity.

• What God is in 1 Samuel, Jesus is in Hebrews—one, unified, unchanging Lord.


One Seamless Portrait

1 Samuel 15:29 shows the Father as unchanging; Hebrews 13:8 shows the Son likewise unchanging.

• These verses fit together like two halves of a clasp, confirming the unity of the Godhead.

• Cross-references reinforce the theme:

Malachi 3:6: “For I, the LORD, do not change.”

Numbers 23:19: “God is not a man, that He should lie, nor a son of man, that He should change His mind.”

James 1:17: “...the Father of lights, in whom there is no variation or shifting shadow.”


Implications for Daily Life

• Assurance in Salvation

– Because Jesus never changes, the salvation He purchased (Hebrews 7:25) remains secure.

• Stability in Promise

– Every biblical promise holds the same force today as when first spoken (2 Corinthians 1:20).

• Consistency in Character

– God’s holiness, love, and justice remain in perfect balance; He never compromises one attribute to exercise another.

• Confidence in Prayer

– We approach a Father who responds consistently with His word, not on impulse (1 John 5:14).


Living in Light of His Constancy

• Anchor your hope to God’s unchanging word each morning; shifting headlines cannot unsettle a fixed heart (Psalm 112:7).

• Measure every new teaching against the timeless truth of Scripture (Acts 17:11).

• Rest when life feels uncertain; the One on the throne is the same One who spoke to Samuel and walked with the disciples.
