Topical Lexicon
Summary

Strong’s Greek number 793 designates a word rendered “unstable” in English versions. It appears exclusively in the Epistle of 2 Peter, where it describes those not firmly grounded in the truth, making them susceptible to error and complicit in the spread of false teaching. By situating the term in Peter’s wider argument, Scripture presents a vivid contrast between the steadfastness produced by knowledge of the Lord Jesus Christ (2 Peter 1:2–10) and the peril faced by souls who lack such stability.

Biblical Usage in 2 Peter

2 Peter 2:14 – False teachers “entice unstable souls.” The term underscores the vulnerability of individuals who have not yet been strengthened in doctrine and moral resolve.
2 Peter 3:16 – The “ignorant and unstable” distort apostolic writings, “as they do the rest of the Scriptures, to their own destruction”. Here the word identifies people whose lack of anchorage leads them to mishandle divine revelation.

Moral and Spiritual Characterization

Unstable persons in 2 Peter are:

1. Morally exposed (2 Peter 2:14)—easily drawn into sensuality and greed.
2. Doctrinally ungrounded (2 Peter 3:16)—unable to handle complex teaching responsibly.
3. Dangerous to others—serving as prey for deceivers and, in turn, propagating distortion.
4. Destined for ruin if not corrected—Peter’s language of “destruction” (3:16) connects instability with eternal consequences.

Historical Setting of 2 Peter

The epistle addresses late–first-century congregations threatened by itinerant teachers who denied the future return of Christ and promoted libertine ethics (2 Peter 3:3–4). In this context, spiritual stability was not optional; it was the safeguard against apostasy. Peter writes shortly before his martyrdom (1:14), urging believers to be “established in the truth” (1:12). The rare term under Strong’s 793 therefore carries weight as a deliberate marker of the peril facing immature disciples in an environment of theological upheaval.

Connection with Old Testament and Early Church Witness

• The image parallels the Septuagint’s depiction of the “double-hearted” (Psalm 12:2) and the “man of a divided mind” in James 1:8.
• Early Christian writers such as Clement of Rome echo the apostolic concern, exhorting believers to be “firmly fixed in the rule of truth.”

Pastoral and Ministry Implications

1. Catechesis: Robust instruction in apostolic doctrine fortifies believers against manipulation.
2. Accountability: Congregational structures that encourage mutual exhortation help steady those prone to wavering (Hebrews 3:13).
3. Discernment: Leadership must identify and refute teaching that preys on the uninstructed, following Peter’s example of exposing error (2 Peter 2:1-3).
4. Compassion: While the term highlights danger, ministry must extend patience and guidance to the spiritually unsteady, “snatching them out of the fire” (Jude 23).

Doctrinal Significance

Peter’s coupling of instability with the distortion of “the rest of the Scriptures” (2 Peter 3:16) affirms the unity and authority of both Old Testament and apostolic writings. Failure to be anchored in the whole counsel of God opens the door to misinterpretation, proving that orthodoxy and orthopraxy stand or fall together.

Practical Exhortations for the Church Today

• Cultivate a comprehensive grasp of Scripture, resisting selective reading that breeds imbalance.
• Promote spiritual disciplines—prayer, fellowship, and obedience—that establish the believer’s heart.
• Guard pulpits and teaching platforms, ensuring that those who instruct others are themselves stable in character and doctrine.
• Encourage believers to “grow in the grace and knowledge of our Lord and Savior Jesus Christ” (2 Peter 3:18), the chief antidote to instability.

Related Terms and Concepts

Steadfastness (1 Corinthians 15:58), firm foundation (2 Timothy 2:19), rooted and built up (Colossians 2:7), maturity (Ephesians 4:14–15). Together these passages construct a biblical theology of spiritual stability that counters the peril signified by Strong’s 793.
