Passage
But you did not learn Christ in this way—
But you did not learn Christ in this way—
Ephesians 4:18 being darkened in their mind, alienated from the life of God because of the ignorance that is in them, because of the hardness of their heart.
Ephesians 4:19 And they, having become callous, have given themselves over to sensuality for the practice of every kind of impurity with greediness.
Ephesians 4:20 But you did not learn Christ in this way—
Ephesians 4:21 if indeed you heard Him and were taught in Him, just as truth is in Jesus,
Ephesians 4:22 to lay aside, in reference to your former conduct, the old man, which is being corrupted in accordance with the lusts of deceit,
The verse centers on "learn" and "christ". It is saying that the verse draws attention to "learn" and "christ", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 19's "And they having become callous have given..." into verse 21's "if indeed you heard Him and were...", so "learn" and "christ" 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 "learn" and "christ" with trust shaped by these words, not by a vague optimism outside the passage.
