### Biblical Occurrences & Contextual Analysis
In the biblical narrative, `{{G2644}}` is used in both divine and human contexts. Its primary application describes God's action of **reconciling** the world to Himself through Christ [[2 Corinthians 5:19]].

### Related Words & Concepts

* `{{G2190}}` **echthrós** (enemy, foe): This term defines the state of hostility that existed prior to reconciliation. Scripture makes a direct contrast, stating that "when we were **enemies**, we were reconciled to God" [[Romans 5:10]].

It explains the transition from a state of being an **enemy** to one of peace with God, accomplished through Christ's death [[Romans 5:10]] and resulting in a ministry that calls all people to be **reconciled** to Him.
