### Core Meaning & Semantic Range
The Greek adjective βέβαιος (bébaios, `{{G949}}`) derives from the base of βάσις (basis), signifying a foundation or base. This etymological root immediately conveys a sense of stability, firmness, and security. Its core meaning encompasses that which is stable, secure, and unshakeable, whether literally or figuratively. Semantically, βέβαιος extends to denote reliability, certainty, trustworthiness, and validity. It describes something that is fixed, guaranteed, and not subject to change or invalidation. The term implies an inherent strength and an enduring quality, standing in contrast to anything that is fleeting, uncertain, or easily overthrown.
### Biblical Occurrences & Contextual Analysis
The term βέβαιος appears consistently in the New Testament, often highlighting the steadfastness of divine promises and the necessity of human endurance.
* In [[Romans 4:16]], Paul uses βέβαιος to describe the certainty of God's promise to Abraham, emphasizing that its reliability rests on grace through faith, not on human works, thus making it "sure" (βέβαιος) for all who believe.
* [[2 Corinthians 1:7]] speaks of the apostle's "stedfast" (βέβαιος) hope concerning the Corinthians, indicating a firm and unwavering confidence in their spiritual welfare.
* The Epistle to the Hebrews frequently employs βέβαιος to underscore the unalterable nature of God's dealings and the security of the New Covenant.
* In [[Hebrews 2:2]], the "word spoken by angels" (the Old Covenant law) is described as "stedfast" (βέβαιος), highlighting its binding authority and the certainty of its consequences. This sets a precedent for the even greater authority of the New Covenant.
* [[Hebrews 3:6]] and [[Hebrews 3:14]] exhort believers to hold their "confidence" and "hope" "firm" (βέβαιος) unto the end, emphasizing the need for enduring steadfastness in their faith to remain partakers of Christ.
* Perhaps most powerfully, [[Hebrews 6:19]] describes the Christian hope as "an anchor of the soul, both sure and stedfast" (βέβαιος). This imagery conveys absolute security and immutability, grounded in God's unchangeable oath and promise.
* [[Hebrews 9:17]] uses βέβαιος to describe a testament or will as being "of force" (βέβαιος) only after the death of the testator. This legal analogy is crucial for understanding the binding and effective nature of the New Covenant, ratified by Christ's death.
* Finally, in [[2 Peter 1:19]], Peter declares that believers have "a more sure word of prophecy" (βέβαιος), asserting the superior reliability and trustworthiness of prophetic Scripture, even over eyewitness accounts of transfiguration. This underscores the divine origin and unwavering truthfulness of God's revealed word.

### Theological Significance
The theological significance of βέβαιος is profound, centering on the absolute reliability of God and His redemptive plan.
1. **Divine Reliability and Immutability:** At its core, βέβαιος points to the unwavering character of God. His promises, His covenant, and His very counsel are βέβαιος, meaning they are utterly trustworthy, unchangeable, and guaranteed. This provides the ultimate foundation for faith and hope.
2. **Certainty of the New Covenant:** The term is particularly significant in Hebrews, where it emphasizes the superior and unshakeable nature of the New Covenant established through Christ's sacrifice. Unlike the Old Covenant, which had limitations, the New Covenant is eternally "of force" (βέβαιος) because it is sealed by the death of the eternal Son, making salvation and access to God a secure reality.
3. **The Anchor of Hope:** The description of hope as a "sure and stedfast anchor" (βέβαιος) in [[Hebrews 6:19]] is a powerful theological statement. Christian hope is not a mere wish, but a firm, unshakeable assurance, grounded in God's immutable oath and the accomplished work of Christ, who has entered "within the veil." This hope provides stability for the soul amidst life's storms.
4. **Authority of God's Word:** The "more sure word of prophecy" (βέβαιος) in [[2 Peter 1:19]] affirms the absolute divine authority and unwavering truthfulness of Scripture. It is presented as a reliable guide in darkness, superior even to sensory experience, because it originates from God.
5. **Exhortation to Steadfastness:** While God is βέβαιος, the term also serves as an exhortation for believers. We are called to be βέβαιος in our faith, confidence, and hope, enduring to the end. This steadfastness is not a means of earning salvation but a demonstration of the authenticity and enduring nature of a faith that is truly anchored in the βέβαιος God.
### Summary
βέβαιος (bébaios, `{{G949}}`) signifies that which is firm, stable, reliable, and certain. Rooted in the idea of a secure foundation, its usage in the New Testament primarily highlights the absolute trustworthiness of God, His promises, and His covenants. It underscores the unchangeable nature of His divine counsel and the guaranteed efficacy of the New Covenant established through Christ. For the believer, βέβαιος describes the unshakeable nature of their hope, which serves as a secure anchor for the soul, and also functions as an exhortation to maintain steadfastness in faith and confidence.
