Passage
That ye, being rooted and grounded in loue, may be able to comprehend with al Saints, what is the breadth, and length, and depth, and height:
That ye, being rooted and grounded in loue, may be able to comprehend with al Saints, what is the breadth, and length, and depth, and height:
Ephesians 3:16 That he might graunt you according to the riches of his glorie, that ye may be strengthened by his Spirit in the inner man,
Ephesians 3:17 That Christ may dwell in your heartes by faith:
Ephesians 3:18 That ye, being rooted and grounded in loue, may be able to comprehend with al Saints, what is the breadth, and length, and depth, and height:
Ephesians 3:19 And to knowe the loue of Christ, which passeth knowledge, that ye may be filled with all fulnesse of God.
Ephesians 3:20 Vnto him therefore that is able to do exceeding aboundantly aboue all that we aske or thinke, according to the power that worketh in vs,
The verse centers on "rooted", "grounded", "loue", "able", "comprehend", "saints", "breadth", and "length". It is saying that the verse draws attention to "rooted" and "grounded", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 17's "That Christ may dwell in your heartes..." into verse 19's "And to knowe the loue of Christ...", so "rooted" and "grounded" belong inside that flow. In Ephesians context, the local focus is grace, union with Christ, the church, and new creation.
A plain takeaway is to answer the verse's own emphasis on "rooted" and "grounded" with trust shaped by these words, not by a vague optimism outside the passage.
