Jude 1:21

“Keep yourselves in the love of God, etc.] By which may be meant either the grace and favour of God, that love with which God loves his people; and then the exhortation to the saints to keep themselves in it is, to set it always before them, to keep it constantly in view, to exercise faith on it, firmly believing their interest in it; as also to meditate on it, give themselves up wholly to the contemplation of it, and employ their thoughts constantly about it, which is the foundation of all grace here, and glory hereafter; or to preserve themselves by it, for so the words may be rendered, “preserve yourselves by the love of God”; against Satan's temptations, the snares of the world, and the…”

“In Jde 1:20-21, Jude combines the Father, the Son, and the Holy Ghost: and faith, hope, and love. Keep yourselves--not in your own strength, but "in the love of God," that is, God's love to you and all His believing children, the only guarantee for their being kept safe. Man's need of watching is implied; at the same time he cannot keep himself, unless God in His love keep him. looking for--in hope. the mercy of our Lord Jesus Christ--to be fully manifested at His coming. Mercy is usually attributed to the Father: here to the Son; so entirely one are they.”

“Keep yourselves in the love of God - Still adverting to their own agency. On the duty here enjoined, see the notes at John 15:9. The phrase “the love of God” may mean either God’s love to us, or our love to him. The latter appears, however, to be the sense here, because it is not a subject which could be enjoined, that we should keep up “God’s love to us.” That is a point over which we can have no control, except so far as it may be the result of our obedience; but we may be commanded to love him, and to “keep” ourselves in that love. Looking for the mercy of our Lord Jesus Christ - Particularly when he shall come to receive his people to himself. See the Titus 2:13 note; 2 Peter 3:12 note;…”

“By these means, through his grace, keep yourselves in the love of God, and in the confident expectation of that eternal life which is purchased for you, and conferred upon you, through the mere mercy of our Lord Jesus Christ. Jude 1:22”

“1:21-36 The tribes of Israel failed to keep the covenant; their complacency was rebellion against the Lord, as the rest of the book of Judges shows. 1:21 Though the tribe of Benjamin produced more than its share of heroes (e.g., Ehud, Saul), it was also the nadir of covenant unfaithfulness, in contrast to Judah (see 20:18). Like Judah in its first battle (1:4-8), Benjamin faced challenges from a great people dwelling in a great city, but Benjamin settled for sharing the city with them. Reference to the Lord’s personal presence is absent (cp. 1:19, 22). The Jebusite city remained in Canaanite hands until David’s day. • The phrase to this day highlights either ongoing historical circumstances…”
