(20) Ye have not so learned Christ.--Better, ye did not so learn the Christ. To "learn Christ" is a phrase not used elsewhere; but easily interpreted by the commoner phrase to "know Christ" (see John 14:7; John 14:9; 2Corinthians 5:16; Philippians 3:10), which is still nearer to it in the original, for the word used for "to know" properly means to perceive or "come to know." It would seem that the name "the Christ" is here used emphatically, in distinction from the "Jesus" of the next verse. "To learn the Christ" is to enter into the true meaning of His office as the Anointed Priest, Prophet, and King, or, in one word, as the Mediator, in whom we as Christians escape from the guilt and bondage of the sins described above. Such learning--like the "knowing" of 2Corinthians 5:14--is not "after the flesh," by the mere hearing of the ear, but "after the Spirit," writing Christ upon the heart.

Verse 20. - But ye did not thus learn Christ. "But" emphatic - a great contrast, that must come home to the conscience of every Christian, and to his whole heart and soul. The expression, "learn Christ," is a pregnant one, corresponding to "preaching Christ" (Acts 8:5) - all about Christ, Christ in all his offices, and in all his influence. He that learns Christ appropriates him in the efficacy of his atonement, in the power of his Spirit, in the force of his lessons, and in the spirit of his influence, and finds the whole to be diametrically opposite to the godless world.

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.But ye have not so learned Christ,.... Some distinguish these words, and make two propositions of them, "but ye not so", or "ye are not so, ye have learned Christ"; the first of these propositions has respect to what goes before, and suggests that regenerate persons are not as other men: they do not walk in the vanity of their minds as others, their minds are not empty and vain; but are filled with God, with a saving knowledge of God in Christ, with the fear and love of God, and with Christ, with a spiritual knowledge of him, with faith in him and love to him, and with the Spirit, with his graces and fruits of righteousness; and though there is a great deal of vanity, instability, treachery, and sinfulness in them, yet their walk and the course of their conversation is not according to this: nor are their understandings darkened as others; they are enlightened to see their lost state and condition by nature, the plague of their own hearts, the insufficiency of their own righteousness, the way of life and salvation by Christ, and that salvation from first to last is all of grace; they have some light into the doctrines of the gospel, and have some glimpse of glory; and their light is of an increasing nature: they are not alienated from the life of God as others, but live a life of communion with him, a life of faith upon him, and a life of holiness according to his mind; they are not past feeling as others, they are sensible of sin, and are often pressed down with the weight of it, and groan, being burdened by it; they cannot sin with that delight and pleasure as others do, nor will they plead for it, but confess it with shame and sorrow; nor do they give up themselves to it, and continue in it, and in an insatiable pursuit of it: the reason of all which is, they "have learned Christ": so as to know him as God over all blessed for ever; as the Lord and heir of all things; as the Alpha and Omega of the covenant of grace; as intrusted with all that is near and dear to his Father; as the Father's free gift to men, and as the sinner's Saviour; as the way of access to God and acceptance with him; as the church's head and husband; as the saints' prophet, priest, and King, and as the only Mediator between God and men; and so as to receive him, believe in him, and commit their souls unto him; and so as to embrace his truths, and submit to his ordinances: and this lesson they learn, not in the book and school of nature, nor of carnal reason, nor of the law; but in the book of the covenant, and of the Scripture; and in the school of the church, and under the ministry of the Gospel; for the ministers of the Gospel are the instructors, the instruments of teaching; though the Spirit of God is the efficient cause, the anointing which teacheth all things, and leads into all truth, as it is in Jesus: and this lesson being truly learnt, will teach men to walk differently from others; to deny ungodliness and worldly lusts, and to live soberly, righteously, and godly.
