Nearby Context

Ephesians 4:19 who being past feeling gave themselves up to lasciviousness, to work all uncleanness with greediness.

Ephesians 4:20 But ye did not so learn Christ;

Ephesians 4:21 if so be that ye heard him, and were taught in him, even as truth is in Jesus:

Ephesians 4:23 and that ye be renewed in the spirit of your mind,

Study Lenses

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

The nearby context moves from verse 20's "But ye did not so learn Christ..." into verse 22's "that ye put away as concerning your...", so "heard" and "taught" 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 "taught" with trust shaped by these words, not by a vague optimism outside the passage.
