Passage
For this reason I bow my knees to the Father [of our Lord Jesus Christ],
For this reason I bow my knees to the Father [of our Lord Jesus Christ],
Ephesians 3:12 in whom we have boldness and access in confidence by the faith of him.
Ephesians 3:13 Wherefore I beseech [you] not to faint through my tribulations for you, which is your glory.
Ephesians 3:14 For this reason I bow my knees to the Father [of our Lord Jesus Christ],
Ephesians 3:15 of whom every family in [the] heavens and on earth is named,
Ephesians 3:16 in order that he may give you according to the riches of his glory, to be strengthened with power by his Spirit in the inner man;
The verse centers on "reason", "knees", "father", "lord", "jesus", and "christ". It is saying that the verse draws attention to "reason" and "knees", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 13's "Wherefore I beseech you not to faint..." into verse 15's "of whom every family in the heavens...", so "reason" and "knees" 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 "reason" and "knees" with trust shaped by these words, not by a vague optimism outside the passage.
