For every one that useth milk is unskilful in the word of righteousness: for he is a babe.
For everyone that useth milk,.... And sits down contented with the first principles of the Gospel, such as are easily taken in and digested; or makes use of the ceremonial law, as a schoolmaster to teach him the Gospel:
is unskilful in the word of righteousness; the Gospel, which is a doctrine of righteousness; not of works of righteousness done by men, and of justification by them, or of a man's own righteousness; but of the pure, perfect, and everlasting righteousness of Christ: and it is called so, because it is the means of stripping a man of his own righteousness; and of revealing the righteousness of Christ unto him; and of working faith in him to lay hold upon it; and of discovering the agreement there is between the righteousness of Christ, and the justice of God; and of teaching men to live soberly, righteously, and godly: and such are unskilful in it, who either have no knowledge of the doctrine of justification; of the matter of it, Christ's righteousness; of the form of it, by imputation; and of the date of it, before faith: or have a very confused notion of it, joining their own works with Christ's righteousness, for justification, as many judaizing professors did; or who, if they have a notional knowledge of it, have no practical concern in it; do not believe with the heart unto righteousness; have not the experience, sweetness, and power of this doctrine upon them; and do not live lives agreeable to it:
for he is a babe. This word is used sometimes by way of commendation, and is expressive of some good characters of the saints; such as harmlessness and inoffensiveness, humility, and meekness, a desire after the sincere milk of the word, freedom from rancour and malice, hypocrisy and guile; but here it is used by way of reproach, and denotes levity and inconstancy, ignorance and non-proficiency, want of digestion of strong meat, and incapacity to take care of themselves, as standing in need of tutors and governors.
