Revelation 3:19

As many as I love I rebuke and chasten,.... The persons the objects of Christ's love here intended are not angels, but the sons of men; and these not all of them, yet many of them, even all who are his own by his Father's gift and his own purchase; and who are called his church, and sometimes represented as such who love him and obey his commands: the instances of his love to them are many; as his suretyship engagements for them, his assumption of their nature, dying in their room and stead, paying their debts, procuring their peace and pardon, bringing in a righteousness for them, purchasing their persons, his intercession for them, preparations in heaven, supplies of grace, and frequent visits in a kind and familiar manner; and as for the nature of his love, it is free and sovereign, everlasting and immutable, and it is matchless and inconceivable, it is strong and affectionate, and as his Father loved him; and such are rebuked by Christ, not in a way of wrath, but in a tender manner, in order to bring them under a conviction of their sin and of their duty, and of their folly in trusting in, or loving any creature more than himself, and of all their wrong ways; and they are chastened by him, not in a vindictive, but in a fatherly way, which is instructive and teaching to them, and for their good. This seems to refer to some afflictions which Christ was about to bring upon this church, by some means or another, to awaken her out of her sloth and security, and which would be in love to her, and the end be to rouse her zeal and bring her to repentance. Some think this respects the Gog and Magog army, which will encompass the camp of the saints, and the beloved city; but that will not be till after the thousand years' reign, and besides will be no affliction to them; rather it designs the unchurching them, signified by spewing them out of his mouth, Revelation 3:16;

be zealous, therefore, and repent; zeal was what was wanting in this church; which is nothing else than hot, fervent, and ardent love, love in a flame; whereas she was neither cold nor hot, but lukewarm, Christ would have her be "zealous" for God; for his cause and interest, for his Gospel, ordinances, and the discipline of his house, and against everything that is evil; against all false worship, all errors in doctrine, all sin and iniquity; and to be zealous of good works, and in the worship of God, both private and public: and "repent"; in an evangelical way, of her lukewarnmess, remissness, and supineness; of her pride, arrogance, and vain boastings of herself; and of her self-sufficience, self-dependence, and self-confidence.
