### Biblical Occurrences & Contextual Analysis
In the biblical narrative, `{{G2925}}` is used in several key contexts. It is famously part of the threefold command to "Ask... seek... **knock**" ([[Matthew 7:7]]; [[Luke 11:9]]), which promises that the one who knocks will have the door opened to them ([[Matthew 7:8]]; [[Luke 11:10]]). The most personal use is in Revelation, where Christ says, "Behold, I stand at the door, and **knock**" [[Revelation 3:20]], offering fellowship to whoever hears His voice and opens the door. The word is also used literally, as when Peter **knocked** at the gate after his miraculous release from prison [[Acts 12:13]], and figuratively in parables about watchfulness and readiness ([[Luke 12:36]]; [[Luke 13:25]]).
### Related Words & Concepts

* `{{G455}}` **anoígō** (to open): This is the direct response promised to one who knocks. It signifies access being granted, whether to a physical house or to a relationship with God [[Luke 11:9]].
* `{{G2374}}` **thýra** (door): This is the portal or entrance where the action of knocking takes place. It functions literally and figuratively as a barrier that can be opened through appeal ([[Revelation 3:20]]; [[Acts 12:13]]).

### Theological Significance
The theological weight of `{{G2925}}` is significant, highlighting key aspects of the divine-human relationship.
* **Divine Initiative and Fellowship:** Christ's action of standing at the door to **knock** [[Revelation 3:20]] illustrates God's initiative in seeking a relationship. The promised result for the one who opens the door is not just entry, but intimate fellowship, as Christ promises to **sup** `{{G1172}}` with that person.
* **Persistent Faith:** The triad of "ask, seek, **knock**" [[Luke 11:9]] presents knocking as the most active and persistent form of prayer. It implies an unwavering faith that there is someone on the other side of the door who will answer, as stated in the promise, "to him that knocketh it shall be opened" [[Luke 11:10]].
* **Urgency and Finality:** A parable in Luke warns that there comes a time when the master of the house has shut `{{G608}}` the door, and those who then **knock** will be told, "I know you not" [[Luke 13:25]]. This underscores that the opportunity to respond to God's invitation is not indefinite.
### Summary
In summary, `{{G2925}}` moves beyond its simple definition of **knock**. It serves as a powerful metaphor for humanity's role in seeking God. The word encapsulates a spectrum of spiritual realities, from the promise of access through persistent prayer [[Matthew 7:7]] to the personal invitation from Christ for intimate fellowship [[Revelation 3:20]]. It simultaneously carries a sober warning that the door of opportunity will not remain open forever, making the act of knocking a timely and critical expression of faith.
