God's nature in "swore by Himself"?
What does "swore by Himself" reveal about God's nature and reliability?

The Immediate Setting in Hebrews 6:13

“ When God made His promise to Abraham, since He had no one greater to swear by, He swore by Himself ”.

• Context: The writer is encouraging believers not to drift but to hold fast to hope (6:11-12).

• Argument: If even Abraham could anchor his faith in God’s self-guaranteed oath, so can we.


Why God Uses an Oath at All

• Humans add an oath to stop every dispute (6:16).

• God does not need to convince Himself, but He graciously stoops to our level to give “strong encouragement” (6:18).

• By adding an oath to His promise, He gives double assurance:

– Promise (God’s word).

– Oath (God’s self-attestation).


“Swore by Himself” — What It Shows about His Nature

• Supreme Greatness

– No authority higher exists; He is the ultimate reference point (Isaiah 45:22-23).

• Absolute Holiness

– His own character is flawless, so His name is an unbreakable guarantee (Psalm 89:35).

• Self-Existence (Aseity)

– He depends on nothing outside Himself (Exodus 3:14).

• Immutability

– He does not change; therefore His oath cannot change (Malachi 3:6).

• Truthfulness

– “God is not a man, that He should lie” (Numbers 23:19).


“Swore by Himself” — What It Shows about His Reliability

• Two Unchangeable Things (Hebrews 6:18)

– His promise.

– His oath.

– “ …in which it is impossible for God to lie.”

• His Own Honor Is at Stake

– To break His oath would violate His very being; therefore it cannot happen (2 Timothy 2:13).

• Eternal Security for the Heirs of Promise

– Because the oath was made to Abraham’s seed, all who belong to Christ share in the certainty (Galatians 3:29).

• Hope Anchored “Behind the Veil”

– Our hope is as secure as the glorified Christ Himself (Hebrews 6:19-20).


Echoes of the Self-Backed Oath through Scripture

Genesis 22:16-17 — “By Myself I have sworn… I will surely bless you.”

Psalm 110:4 — The priesthood of Messiah confirmed: “The LORD has sworn and will not change His mind.”

Isaiah 54:9-10 — God’s covenant of peace compared to Noah: unwavering, immovable.

Jeremiah 31:35-37 — Only if the cosmos can be measured will His covenant fail.


Living in the Confidence of His Self-Guaranteed Promise

• Rest from Anxiety

– If God’s own honor secures the promise, worry is dethroned.

• Boldness in Prayer

– Approach “the throne of grace” knowing the oath-keeping God welcomes you (Hebrews 4:16).

• Perseverance in Obedience

– Abraham’s patient endurance (6:15) becomes our template.

• Assurance of Salvation

– Our anchor is fixed in God, not in fluctuating feelings or performance.

Because God “swore by Himself,” His promises are as unbreakable as His own nature. That truth steadies the soul and fuels a hope that endures to the end.
