στερεός

Core Meaning & Semantic Range

The Greek word stereós, represented by G4731, means solid or stable. Derived from G2476 (hístēmi), meaning "to stand," it carries the idea of being stiff, firm, and unshakeable. It appears 4 times across 4 unique verses in the Bible and is translated as "sure," "strong," or "stedfast."

Biblical Occurrences & Contextual Analysis

In its scriptural applications, G4731 describes both doctrinal truth and spiritual maturity. In 2 Timothy 2:19, it affirms that the foundation of God "standeth sure," highlighting the unwavering nature of God's promises. The book of Hebrews uses the term to contrast the "milk" of basic principles with the "strong meat" suitable for the spiritually mature (Hebrews 5:12, Hebrews 5:14). Finally, it is used to call believers to be stedfast in the faith, enabling them to resist their adversary 1 Peter 5:9.

Related Words & Concepts

Several related words clarify the concept of stability and firmness:

• G2476 hístēmi: As the root word for G4731, it means to stand. It is used in 2 Timothy 2:19 to describe how the foundation "standeth" sure.
• G2310 themélios: Meaning a foundation, this word is directly paired with G4731 to illustrate the unshakeable nature of God's truth 2 Timothy 2:19.
• G436 anthístēmi: This term means to stand against, i.e. oppose. It is used in 1 Peter 5:9, commanding believers to "resist" the devil, which is made possible by being "stedfast" G4731 in the faith.

Theological Significance

The theological weight of G4731 is seen in its application to core Christian principles.

• Doctrinal Certainty: The word establishes the absolute reliability of God's truth. In 2 Timothy 2:19, the "foundation of God standeth sure," secured by a divine "seal" G4973, indicating it is immoveable and unchangeable.
• Spiritual Maturity: It is used as a marker for spiritual growth. Hebrews contrasts the "first principles" G4747 for new believers with the "strong meat" of deeper doctrine for those who are "of full age" G5046 and have their senses exercised Hebrews 5:12-14.
• Steadfast Resistance: The term defines the posture of a believer against spiritual adversity. To "resist" G436 the devil, one must be "stedfast in the faith" G4102, showing that stability is a prerequisite for effective spiritual warfare 1 Peter 5:9.

Summary

In summary, G4731 is a concise but powerful term in the New Testament. Though appearing only four times, it provides a crucial framework for understanding stability in the Christian life. From the sure foundation of God's promises to the strong meat of mature doctrine and the stedfast resolve needed in faith, stereós communicates a non-negotiable firmness that is both a gift from God and a goal for every believer.
