But strong meat belongeth to them that are of full age,
&c.] Or perfect; see ( 1 Corinthians 2:6 ) . This does not intend a perfection of justification; for though some have a greater degree of faith than others, and a clearer discovery of their justification, yet babes in Christ are as perfectly justified as more grown and experienced believers; nor a perfection of sanctification, for there is no perfection of holiness but in Christ; and though the work of sanctification may be in greater perfection in one saint than in another, yet all are imperfect in this life; and as to a perfection of parts, babes have this as well as adult persons: but it designs a perfection of knowledge; for though none are entirely perfect, yet some have arrived to a greater degree of the knowledge of Gospel mysteries than others, and to these the strong meat of the Gospel belongs; they are capable of understanding the more mysterious parts of the Gospel; of searching into the deep things of God; and of receiving and digesting the more sublime truths of the Christian religion: even those who by reason of use, have their senses exercised to
discern both good and evil;
that is, their spiritual senses, the internal senses of the understanding and judgment, signified by external ones; as by seeing the Son; hearing the voice of Christ; savouring or smelling a sweet odour in the things of God, and Christ; tasting that the Lord is gracious; feeling and handling the word of life, as these are held forth in the everlasting Gospel: and these being exercised on their proper object, by use, an habit is contracted; and such are qualified for discerning, as between moral good and evil, and the worse and better state of the church, and between law and Gospel, so between the doctrines of Christ, and the doctrines of men; who find they differ: the doctrines of Christ such experienced persons find to be good, wholesome, nourishing, and salutary; and the doctrines of men to be evil, to eat, as does a canker, and to be pernicious, poisonous, and damnable; and the discernment they make, and the judgment they form, are not according to the dictates of carnal reason, but according to the Scriptures of truth, and their own experience.
