The Greek word bathýnō, represented by G900, means to deepen. It is derived from the word βαθύς and is used to convey the idea of making something deep. This word is exceptionally rare, appearing only 1 time in 1 unique verse in the entire Bible.
The single use of G900 appears in the parable of the wise and foolish builders in Luke 6:48. In this verse, a wise man building a house is described as one who digged and went deep to lay a foundation on a rock. This deliberate action to deepen the foundation is contrasted with the foolish builder and is presented as the reason the house could not be shaken by a flood. The word emphasizes the effort and thoroughness required to establish a secure and stable structure.
Several related words provide a fuller context for the action and purpose of going deep:
- G4626 skáptō: This word means to dig. It is used directly with G900 to describe the physical labor of the wise builder in excavating the ground for his house Luke 6:48.
- G2310 themélios: This term for foundation represents the goal of digging deep. It is what the wise man lays on the rock Luke 6:48. This word is used figuratively elsewhere to refer to Jesus Christ as the only true foundation 1 Corinthians 3:11 and the basis of the church Ephesians 2:20.
- G2311 themelióō: Meaning to lay a basis for, this verb describes the act of founding or settling something firmly. It is used to state that the wise man's house was founded upon a rock Luke 6:48 and is also used figuratively for being grounded in faith and love (Colossians 1:23, Ephesians 3:17).
The theological significance of G900 is tied directly to its context in the parable. It highlights a critical aspect of discipleship:
- Deliberate Preparation: To deepen is not a passive state but an active, strenuous effort. It illustrates that a strong spiritual life, one that can withstand trials, requires intentional work to build upon a solid base.
- Establishing a Foundation: The action of going deep is inseparable from its purpose: to lay a foundation G2310 on the rock. This connects the word to the core Christian concept of building one's life on the unshakeable truth of Christ and His teachings.
- Ensuring Stability: The result of this deep work is a structure that is founded G2311 securely and cannot be shaken by the "flood" or "stream" Luke 6:48. This conveys the assurance and steadfastness that comes from a life built with depth and foresight.
In summary, while G900 is used only once, its placement within a key parable gives it significant weight. The word bathýnō provides a vivid picture of the necessary labor and commitment required for a stable spiritual life. It moves beyond a simple architectural instruction to become a powerful metaphor for the disciple's duty to build their faith with depth and purpose on the rock of God's word, ensuring it can endure any adversity.
