Passage
In whom we have boldness and access with confidence by the faith of him.
In whom we have boldness and access with confidence by the faith of him.
Ephesians 3:10 To the intent that now unto the principalities and powers in heavenly places might be known by the church the manifold wisdom of God,
Ephesians 3:11 According to the eternal purpose which he purposed in Christ Jesus our Lord:
Ephesians 3:12 In whom we have boldness and access with confidence by the faith of him.
Ephesians 3:13 Wherefore I desire that ye faint not at 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,
The verse centers on "faith", "boldness", "access", and "confidence". 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 11's "According to the eternal purpose which he..." into verse 13's "Wherefore I desire that ye faint not...", so "faith" and "boldness" 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 "boldness" with trust shaped by these words, not by a vague optimism outside the passage.
