Ephesians 4:21 If so be that ye have heard him, and have been taught by him, as the truth is in Jesus:

Study Lenses

The verse centers on "heard", "been", "taught", "truth", and "jesus". It is saying that the verse draws attention to "heard" and "been", so its meaning should be read from those terms before moving to application.

The nearby context moves from verse 20's "But ye have not so learned Christ..." into verse 22's "That ye put off concerning the former...", so "heard" and "been" 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 "heard" and "been" with trust shaped by these words, not by a vague optimism outside the passage.
