Study Lenses

The verse centers on "faith", "christ", "dwell", "hearts", "rooted", "grounded", and "love". It is saying that salvation is received as God's gift through faith, so boasting is pushed out by the wording itself.

The nearby context moves from verse 16's "That he would grant you according to..." into verse 18's "May be able to comprehend with all...", so "faith" and "christ" 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 "faith" and "christ" with trust shaped by these words, not by a vague optimism outside the passage.
