### Core Meaning & Semantic Range
The Greek adjective ἀσφαλής (G804) is a compound word formed from the privative particle α- (indicating negation or absence) and the verb σφάλλω (to cause to fall, to stumble, to fail). Thus, its core meaning is "not failing," "unfailing," or "not liable to fall." This etymological root gives rise to a semantic range encompassing:
1. **Physical Security:** A state of being safe from danger, stable, or firmly established.
2. **Intellectual Certainty:** Reliable, trustworthy, or definite knowledge; facts that are beyond doubt.
3. **Spiritual Steadfastness:** Though less direct, the concept of being unshakeable or firm, particularly in the context of divine promises or hope.
### Biblical Occurrences & Contextual Analysis
The term ἀσφαλής appears five times in the New Testament, revealing its diverse applications:
* In **Acts 21:34**, the Roman tribune, unable to ascertain the "certainty" (τὸ ἀσφαλές) of the facts amidst the crowd's uproar regarding Paul, orders him to the barracks. Here, ἀσφαλής refers to reliable and definite information.
* Similarly, in **Acts 22:30**, the tribune seeks to know "the real reason" or "the certain facts" (τὸ ἀσφαλές) for the accusations against Paul, indicating a desire for accurate and trustworthy information.
* **Acts 25:26** sees Festus admitting to King Agrippa that he has "nothing certain" (οὐδὲν ἀσφαλές) to write to the emperor concerning Paul's case, again highlighting the need for definite and substantiated evidence.
* In **Philippians 3:1**, Paul states that writing the same things to the Philippians is "no trouble" for him and is "safe" (ἀσφαλές) for them. This suggests that repetition of sound doctrine provides spiritual security and protection against error, ensuring their steadfastness in the faith.
* The most profound theological use is found in **Hebrews 6:19**, where Christian hope is described as "an anchor for the soul, firm and secure" (ἀσφαλῆ). This metaphor emphasizes the absolute reliability and unshakeableness of the hope that believers possess, a hope grounded in God's unchanging promise and oath, and secured by Christ's entrance into the heavenly sanctuary.
### Related Words & Concepts
ἀσφαλής is part of a cluster of Greek words conveying reliability and firmness:
* Its immediate noun form is ἀσφάλεια (`{{G803}}`), meaning "security" or "certainty," as seen in [[Luke 1:4]] where Theophilus is assured of the "certainty" of the things he has been taught.
* Other related terms include βέβαιος (`{{G949}}`), which also means "firm," "steadfast," or "sure," often used in reference to promises or covenants (e.g., [[Hebrews 2:2]]).
* πιστός (`{{G4103}}`), meaning "faithful" or "trustworthy," often describes God's character and the reliability of His word.

### Theological Significance
The theological significance of ἀσφαλής lies primarily in its application to the nature of God, the certainty of salvation, and the steadfastness of Christian hope.
1. **God's Reliability:** The word implicitly testifies to the unwavering character of God. Just as facts can be "certain," so too are God's promises and His very being. He is not one to fail or stumble.
2. **Certainty of Revelation:** In the Acts passages, the pursuit of "certain" facts underscores the New Testament's emphasis on truth and reliable testimony, particularly concerning the events of Christ's life and the apostles' message. The gospel is presented not as speculation, but as a message of demonstrable certainty.
3. **The Anchor of Hope:** The usage in [[Hebrews 6:19]] is arguably the most profound. Here, ἀσφαλής describes the unbreakable nature of the believer's hope. This hope is not a mere wish but a spiritual anchor, firmly fixed in the unchangeable counsel of God and secured by Christ, who has entered the inner sanctuary as our High Priest. This provides profound assurance and stability for the soul amidst life's storms. It points to the absolute security of the believer's position in Christ, grounded in divine faithfulness rather than human merit or fluctuating circumstances.
### Summary
The Greek word ἀσφαλής (G804) fundamentally signifies "secure," "certain," or "safe," stemming from its etymological meaning of "not failing." In the New Testament, its usage ranges from describing the reliability of information and facts in legal and investigative contexts (Acts) to the spiritual safety found in adhering to sound doctrine (Philippians). Most significantly, in Hebrews, ἀσφαλής powerfully portrays Christian hope as an "anchor for the soul, firm and secure," highlighting the unshakeable and trustworthy nature of God's promises and the work of Christ. This word thus underscores the divine faithfulness as the ultimate source of certainty and security for the believer, providing an unwavering foundation for faith and life.
