Proverbs 4:6

Forsake her not, and she shall preserve thee
That is, Wisdom, or Christ. Men may be said to forsake Christ when they forsake the assembly of his church and people, which are his other self; when they forsake his ministers, his ambassadors, and representatives; when they forsake his word and ordinances; when they drop the doctrines of the Gospel, or depart from them; when they quit the profession they have formerly made. Nominal believers and formal professors may forsake him finally and totally; true believers only partially and for a time, through the weakness of the flesh, the temptations of Satan, the snares of the world, and the prevalence of corruption; and therefore such an exhortation is necessary, and ought to be regarded. To forsake Christ is a very great evil; it is against a man's own interest, and is of dangerous consequence, and therefore to be guarded against; to abide by him, his truths and ordinances, is very commendable; such shall be "preserved" by him safe to his kingdom and glory; love her, and she shall keep thee;
Christ is to be loved for the excellencies and perfections of his nature; for the loveliness of his person; for the love he has showed to his people; for what he in love has done and suffered for them, and is now doing; for the fulness of his grace and salvation, and the suitableness of them to them; for the communion he indulges them in with himself; for the relations of an head, husband, father, brother, and friend, he stands in to them: and also under the character of Wisdom, he being the only wise God and their Saviour, the Wisdom of God and Wisdom to them; and whose Gospel is the Wisdom of God in a mystery. He is to be loved, all of him and that belong unto him, and above all creatures and things, ardently, sincerely, and constantly; and such lovers of him shall be "kept" by him from the evil of the world; from the power and dominion of sin, and condemnation by it; from being destroyed by Satan, and his temptations; and from a final and total falling away, so as not to perish everlastingly; they are kept in his own hands, in his Father's love and his own, in the everlasting covenant; and in a state of grace, of sanctification, justification, and adoption. Not that loving Christ, and cleaving to him, are the causes of this preservation; but his love, grace, and power; yet these are descriptive of the persons kept and preserved: and the preservation and keeping of them is used as an argument to love him, and cleave unto him.
