| Geneva Study Bible {13} But ye have not so learned Christ; (13) Here follows the contrary part concerning men who are regenerated by the true and living knowledge of Christ, who have other principles by which they act that are very different, that is, holy and honest desires, and a mind completely changed by the power of the Holy Spirit, from which proceeds also like effects, as a just and holy life indeed. People's New Testament 4:20 But ye have not so learned Christ. You are Gentiles by birth, like dthose just described, but you have learned otherwise from Christ. Wesley's Notes 4:20 But ye have not so learned Christ - That is, ye cannot act thus, now ye know him, since you know the Christian dispensation allows of no sin. Jamieson-Fausset-Brown Bible Commentary 20. learned Christ-(Php 3:10). To know Christ Himself, is the great lesson of the Christian life: this the Ephesians began to learn at their conversion. "Christ," in reference to His office, is here specified as the object of learning. "Jesus," in Eph 4:21, as the person. Matthew Henry's Concise Commentary 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. |
