Therefore, my brethren
Not in a natural but spiritual relation; having the same Father, being of the same family, and household of faith: seeing that on the one hand there were false teachers, who stand described by various characters in the preceding chapter, by whom they were in danger of being carried away from the simplicity of the Gospel; and on the other hand, such were the conduct and conversation of the apostle, and other true believers, and such were their expectations of Christ from heaven, and of happiness from him as there expressed; therefore he exhorts to steadfastness in him, and that under the most tender, affectionate, and endearing appellations; given in the uprightness of his soul, without any manner of flattery, to signify his strong affection for them, and to engage them to attend the more to what he was about to exhort them to; and which arose from pure love to them, an hearty concern for their good, and the honour of Christ Jesus:
dearly beloved:
as belonging to Christ, interested in him, members of him, redeemed by him, and bearing his image; and as his brethren, and so not loved with a carnal, but spiritual love:
and longed for;
to see them, converse with them, and impart some spiritual gift to them; being the excellent in the earth, as other saints, towards whom was his desire, and with whom was all his delight. These epithets are joined with the word "brethren", in the Vulgate Latin, Syriac, and Arabic versions, and read thus, "my dearly beloved, and longed for brethren"; and in the Ethiopic version, "our beloved brethren": to which are added,
my joy and crown;
they were matter of joy to him, as he had reason to hope well of them; yea, to be confident that the good work was begun, and would be carried on in them; and that they had hitherto continued in the doctrine of the Gospel, and walked worthy of it; and they were his "crown", as they were seals of his ministry; and whom he valued more, and reckoned a greater honour and ornament to him, than the richest diadem, set with the most costly jewels and precious stones, and which he hoped and believed would be his crown of rejoicing another day; when he, with them, should stand at the hand of Christ triumphing, as victors crowned, ever sin, Satan, the world, death, and hell:
so stand fast in the Lord;
or "by the Lord"; by his power and strength, which is only able to make to stand fast; saints are liable to failing, and would fall, were they not upheld with his right hand, and kept by his power; they only stand fast, as they stand supported by his strength, trusting in his might, and leaning on his arm. Christ is the only foundation where they can stand safe and sure; and such as are rooted and grounded, and built up in him, are established and stand; though they are still in need of being exhorted to hold the head, abide by him, and cleave unto him; to stand fast in his grace, exercising the graces of faith, hope, and love upon him; in the liberty of Christ, in opposition to the bondage of the law, false teachers were for bringing them into; and in the doctrine of faith, and not depart from it in any degree, nor give way in the least to the opposers of it, but continue steadfast in it without wavering, and which is chiefly intended here: so the Arabic version renders it, "so stand in the faith of the Lord"; both in the grace faith, and in the doctrine of it, and in the profession of both: see ( 1 Corinthians 16:13 ) . The apostle bids them so stand fast; that is, either as they had hitherto done, or as they had him and others for an example; whose views, conversation, and behaviour, are described in the foregoing chapter:
[my] dearly beloved;
this, which otherwise would be a repetition of what is before said, is by some connected with the former clause, and read thus, "so stand fast my dearly beloved in the Lord"; and contains a reason, both why they were dearly beloved by the apostle, because beloved in and by the Lord; and why it became them to stand fast in him, and abide by him, his truths, ordinances, cause, and interest.
