And how I kept back nothing that was profitable unto you,.... The Syriac version supplies, "to your souls"; to lead them into a true knowledge of the doctrines of the Gospel, and to confirm them in the same, and to preserve them from errors in principle, and immoralities in practice, and to encourage the exercise of every grace, and to instruct them in every branch of duty; nothing of this kind, or which had this tendency, did the apostle dissemble, conceal, or drop, either through sloth and indolence, or through fear of men, or for the sake of reputation, wealth, and friends.
The things the apostle may have chiefly in view are the truths of the Gospel, which are very profitable to the souls of men; such as relate to the knowledge of God, his being, perfections, and persons; as that there are three persons in the Godhead, Father, Son, and Spirit, which is profitable to be known, in order to understand the economy of salvation, in which each person has his distinct concern; and that both the Son and Spirit are equally God with the Father, which accounts for the virtue and efficacy of the blood, righteousness, and sacrifice of Christ, and how safely he may be depended upon for salvation, and how equal the Holy Spirit is to his work and office; likewise such doctrines as relate to the sin of Adam and his posterity in him, to the imputation of the guilt of that sin unto them, and the derivation of a corrupt nature from him, and which respect the impurity and impotence of human nature; all which is profitable, since it accounts for the origin of moral evil, and many of the dispensations of providence in involving those that do not know the right hand from their left in public calamities; and since it shows the necessity of regenerating grace, tends to the humiliation of men, and makes for the magnifying the riches of God's grace: also such doctrines as express the grace of God in man's salvation as the doctrines of God's everlasting love, of election, redemption, justification, pardon, reconciliation, union to Christ, and final perseverance; all which are exceeding profitable, for the peace, comfort, and refreshment of the souls of God's people.
