| Geneva Study Bible Keep yourselves in the love of God, looking for the mercy of our Lord Jesus Christ unto eternal life. People's New Testament Jude 1:21 Keep yourselves in the love of God. By holy lives and prayer. Wesley's Notes 1:21 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. Jamieson-Fausset-Brown Bible Commentary 21. In Jude 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. Matthew Henry's Concise Commentary 1:17-23 Sensual men separate from Christ, and his church, and join themselves to the devil, the world, and the flesh, by ungodly and sinful practices. That is infinitely worse than to separate from any branch of the visible church on account of opinions, or modes and circumstances of outward government or worship. Sensual men have not the spirit of holiness, which whoever has not, does not belong to Christ. The grace of faith is most holy, as it works by love, purifies the heart, and overcomes the world, by which it is distinguished from a false and dead faith. Our prayers are most likely to prevail, when we pray in the Holy Ghost, under his guidance and influence, according to the rule of his word, with faith, fervency, and earnestness; this is praying in the Holy Ghost. And a believing expectation of eternal life will arm us against the snares of sin: lively faith in this blessed hope will help us to mortify our lusts. We must watch over one another; faithfully, yet prudently reprove each other, and set a good example to all about us. This must be done with compassion, making a difference between the weak and the wilful. Some we must treat with tenderness. Others save with fear; urging the terrors of the Lord. All endeavours must be joined with decided abhorrence of crimes, and care be taken to avoid whatever led to, or was connected with fellowship with them, in works of darkness, keeping far from what is, or appears to be evil. |
