Passage
For this cause I bow my knees unto the Father of our Lord Jesus Christ,
For this cause I bow my knees unto the Father of our Lord Jesus Christ,
Ephesians 3:12 in whom we have the freedom and the access in confidence through the faith of him,
Ephesians 3:13 wherefore, I ask <FI>you<Fi> not to faint in my tribulations for you, which is your glory.
Ephesians 3:14 For this cause I bow my knees unto the Father of our Lord Jesus Christ,
Ephesians 3:15 of whom the whole family in the heavens and on earth is named,
Ephesians 3:16 that He may give to you, according to the riches of His glory, with might to be strengthened through His Spirit, in regard to the inner man,
The verse centers on "cause", "knees", "father", "lord", "jesus", and "christ". It is saying that the verse draws attention to "cause" 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 ask FI you Fi not..." into verse 15's "of whom the whole family in the...", so "cause" 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 "cause" and "knees" with trust shaped by these words, not by a vague optimism outside the passage.
