### Core Meaning & Semantic Range
The Greek word **syschēmatízō**, represented by `{{G4964}}`, means to fashion alike or conform to the same pattern. Drawn from roots meaning "to fashion with," it appears **3 times** across **2 unique verses** in the Bible. It carries the figurative meaning of conforming oneself to an external mold or pattern, particularly in behavior and mindset.
### Biblical Occurrences & Contextual Analysis
In its biblical occurrences, `{{G4964}}` is used as a direct negative command to believers. In [[Romans 12:2]], believers are instructed to "be **not conformed** to this world" `{{G165}}`. This is immediately contrasted with the call to be "transformed" `{{G3339}}` by the renewing of the mind. Similarly, [[1 Peter 1:14]] commands believers, as "obedient children" `{{G5218}}` `{{G5043}}`, to be found "not **fashioning yourselves according to** the former lusts" `{{G1939}}` that belonged to their time of "ignorance" `{{G52}}`.
### Related Words & Concepts
Several related words help clarify the patterns believers are called to avoid and the new life they are to embrace:
* `{{G3339}}` **metamorphóō** (to transform (literally or figuratively, "metamorphose")): This is presented as the divine alternative to being conformed. In [[Romans 12:2]], instead of being shaped by the world, a believer is to be internally **transformed**.
* `{{G165}}` **aiṓn** (properly, an age; by extension, the world): This term defines the external system that believers are commanded not to be **conformed** to. It represents the present age with its priorities and way of thinking [[Romans 12:2]].
* `{{G1939}}` **epithymía** (a longing (especially for what is forbidden)): These "former **lusts**" are the old patterns that believers must no longer fashion their lives after. In [[1 Peter 1:14]], they are linked to a past life of spiritual ignorance.
* `{{G52}}` **ágnoia** (ignorance (properly, the quality)): This describes the state in which the "former lusts" `{{G1939}}` operated. The command in [[1 Peter 1:14]] suggests that new life in Christ removes the basis for being fashioned by these old desires.
### Theological Significance
The theological weight of `{{G4964}}` is significant, establishing a core principle of the Christian life.
* **A Call to Distinction:** The command is an explicit call to live a life distinct from the prevailing patterns of the "world" `{{G165}}` and the old self. It forbids passively adopting the ethics and desires of a system opposed to God.
* **The Path to Discerning God's Will:** According to [[Romans 12:2]], non-conformity is a prerequisite for spiritual transformation. Only by resisting the world's mold and being transformed by a renewed mind `{{G3563}}` can a believer "prove what is that good `{{G18}}`, and acceptable `{{G2101}}`, and perfect `{{G5046}}`, will `{{G2307}}` of God `{{G2316}}`."
* **Identity Dictates Behavior:** [[1 Peter 1:14]] connects the command directly to a believer's new identity. As "obedient children" `{{G5218}}` `{{G5043}}`, their behavior should no longer be shaped by past lusts but by their new relationship with God.
### Summary
In summary, `{{G4964}}` is more than a simple command against imitation. It defines a crucial aspect of sanctification, demanding a decisive break from the external patterns of the world and the internal patterns of the "former lusts." By not being conformed, the believer is positioned to undergo a genuine inner transformation, enabling them to understand and live out the will of God.
