Ephesians 4

The walk of 4:1 now has a negative: no longer as the Gentiles, in mental futility. Conversion includes a new mind-path, not only new company.

“No longer” is a break. Grace that taught them Christ also enables them to refuse the empty thinking they once called normal.

Paul testifies in the Lord, not as a life-coach. Futility of mind is the Gentile walk apart from the life of God.

The problem is not merely manners but a mind emptied of true purpose. Those in Christ are summoned to a walk that matches the new creation God has begun.

Darkness, alienation, ignorance, hardness—layered ruin. The heart’s hardness feeds the mind’s night, and distance from God’s life follows.

Arminian interpreters take hardness as culpable, not a neutral disability. Grace can soften and enlighten; persistent hardness remains a free refusal of the life God offers.

The chain runs heart to ignorance to alienation to dark understanding. Life of God is the thing they are shut out from.

Hardness is both guilt and bondage. Without God’s regenerating light, the Gentile walk is not a slight delay in education but deathly distance from His life.

Callousness is chosen: they gave themselves up. Sensuality and greedy impurity are not accidents; they are a handed-over self.

People can yield themselves. The gospel still calls for a different yielding—to Christ—because grace restores the possibility of a new walk.

Given themselves up names willing bondage. Callousness, sensuality, and impurity are a package, not scattered slips.

When God is not the life of the heart, appetite becomes a master. The church is being shown what it has been saved from, not a lifestyle to sample.

Learning Christ has a way, and it is not callous impurity. Discipleship is personal: you learned Him, not merely a system.

Christ taught as He is received. Grace that introduced them to Jesus also defines a path that contradicts their former giving-up of themselves.

The sharp “but” splits two schools. Christ is a curriculum whose content is a person, and that lesson contradicts Gentile futility.

Those God has taught in His Son cannot treat the old walk as an option. Learning Christ is conversion’s classroom, not an elective.

Heard about Him, taught in Him, truth in Jesus: instruction is located inside a living Lord. Doctrine has a proper name.

The truth in Jesus is publicly taught so people may hear and keep learning. Remaining in that teaching is how the new walk stays new.

Hearing and being taught “in him” keep truth from becoming abstraction. Jesus is where truth lives.

Union with Christ is the school. What they heard is not a rumor about religion but the truth that exists in the incarnate Lord.

Put off the old self—the fallen “man” as old as the fall, corrupt through desires that lie. Wesley called those lusts deceitful because they promise what they cannot pay.

Arminian readers treat putting off as a grace-enabled act, not a metaphor to admire. The former manner of life is to be shed, not managed as a pet.

The old self is nature from the womb, deeply corrupt, belonging to the former walk. Deceitful desires are its operating system.

What we put off is a whole person-in-Adam, not a few habits. The command assumes God has already begun the new creation that makes such putting off possible.

Renewal hits the mind’s spirit—the inward attitude of thought. Futility (v. 17) is answered by renovation, not by willpower alone.

God renews, and we seek that renewal. A changed walk requires a changed inner mind, continually offered to the Spirit who makes it new.

Passive tone matters: be renewed. The spirit of the mind is God’s workshop if darkness is to lift.

New ethics start where God recreates thought. The command to walk differently is matched by a promised renovation we cannot perform as a self-upgrade.

Put on what God created: a new self in His likeness, true righteousness and holiness. Clothes language means a whole identity, not a costume for Sundays.

The likeness is true and to be worn. Grace creates the new self; believers put it on in daily trust and obedience, growing into the righteousness that is true, not theatrical.

Created after God’s likeness—this is Genesis language reborn. Righteousness and holiness of truth are the image restored, not a human rebrand.

We put on what God has made. The new self is His workmanship; wearing it is the Christian’s fitting response to the Creator who remade us in Christ.
