17 This I say therefore, and testify in the Lord, that ye henceforth walk not as other Gentiles walk, in the vanity of their mind, 18 Having the understanding darkened, being alienated from the life of God through the ignorance that is in them, because of the blindness [1] of their heart:
17 So I tell you this, and insist on it in the Lord, that you must no longer live as the Gentiles do, in the futility of their thinking. 18 They are darkened in their understanding and separated from the life of God because of the ignorance that is in them due to the hardening of their hearts.
17 Now this I say and testify in the Lord, that you must no longer walk as the Gentiles do, in the futility of their minds. 18 They are darkened in their understanding, alienated from the life of God because of the ignorance that is in them, due to their hardness of heart.
17 And so I insist - and God backs me up on this - that there be no going along with the crowd, the empty-headed, mindless crowd. 18 They've refused for so long to deal with God that they've lost touch not only with God but with reality itself.
17 This I say, therefore, and testify in the Lord, that you should no longer walk as the rest of the Gentiles walk, in the futility of their mind, 18 having their understanding darkened, being alienated from the life of God, because of the ignorance that is in them, because of the blindness of their heart;
17 With the Lord's authority I say this: Live no longer as the Gentiles do, for they are hopelessly confused. 18 Their minds are full of darkness; they wander far from the life God gives because they have closed their minds and hardened their hearts against him.
Matthew Henry's Commentary on Ephesians 4:17-18
Commentary on Ephesians 4:17-24
(Read Ephesians 4:17-24)
The apostle charged the Ephesians in the name and by the authority of the Lord Jesus, that having professed the gospel, they should not be as the unconverted Gentiles, who walked in vain fancies and carnal affections. Do not men, on every side, walk in the vanity of their minds? Must not we then urge the distinction between real and nominal Christians? They were void of all saving knowledge; they sat in darkness, and loved it rather than light. They had a dislike and hatred to a life of holiness, which is not only the way of life God requires and approves, and by which we live to him, but which has some likeness to God himself in his purity, righteousness, truth, and goodness. The truth of Christ appears in its beauty and power, when it appears as in Jesus. The corrupt nature is called a man; like the human body, it is of divers parts, supporting and strengthening one another. Sinful desires are deceitful lusts; they promise men happiness, but render them more miserable; and bring them to destruction, if not subdued and mortified. These therefore must be put off, as an old garment, a filthy garment; they must be subdued and mortified. But it is not enough to shake off corrupt principles; we must have gracious ones. By the new man, is meant the new nature, the new creature, directed by a new principle, even regenerating grace, enabling a man to lead a new life of righteousness and holiness. This is created, or brought forth by God's almighty power.
