Turn, O backsliding children, saith the Lord,.... All of them were children by national adoption, and some by special grace, and yet "backsliders", O monstrous ingratitude! "backsliders", and yet "children", still the relation continues, O marvellous grace! God's own children may backslide, and often do; either in heart, when love waxes cold, faith declines, zeal wanting; when they get into a carnal sleepy frame of spirit, and have not that quick sense of sin, and of duty, as heretofore: or in practice, when private prayer is restrained; public worship is neglected; get into bad company, and fall into gross sins; all which is owing to the prevalence of indwelling sin, the force of Satan's temptations, and the enticing snares of the world; but God will not leave them, he calls unto them again and again to turn unto him by repentance, and to doing their first works; which calls, at length, through powerful grace, become effectual;
"For I am married unto you"; in a civil sense as a nation, (see Jeremiah 31:32), and in a spiritual sense to a remnant of them; Christ is the bridegroom, the church is the bride, which he has secretly betrothed to himself in eternity; openly in time, at the conversion of everyone of them; and will more publicly at the last day, when all are gathered in and prepared for him. This relation, as it is a very near one, so it is very astonishing, considering the disparity between the two parties, and it always continues; love, the bond of it, never alters; the covenant, in which this transaction is carried on, is ever sure; and Christ always behaves agreeably to it; wherefore it is base ingratitude to backslide; and reason there is sufficient why his backsliding spouse should return to him.
