Jude vss 1-4, 16-21 (NJKV)
Greeting to the Called
1 Jude, a bondservant of Jesus Christ, and brother of James,
To those who are called, sanctified by God the Father, and preserved in Jesus Christ:
2 Mercy, peace, and love be multiplied to you.
Contend for the Faith
3 Beloved, while I was very diligent to write to you concerning our common salvation, I found it necessary to write to you exhorting you to contend earnestly for the faith which was once for all delivered to the saints. 4 For certain men have crept in unnoticed, who long ago were marked out for this condemnation, ungodly men, who turn the grace of our God into lewdness and deny the only Lord God and our Lord Jesus Christ.
16 These are grumblers, complainers, walking according to their own lusts; and they mouth great swelling words, flattering people to gain advantage. 17 But you, beloved, remember the words which were spoken before by the apostles of our Lord Jesus Christ: 18 how they told you that there would be mockers in the last time who would walk according to their own ungodly lusts. 19 These are sensual persons, who cause divisions, not having the Spirit.
Maintain Your Life with God
20 But you, beloved, building yourselves up on your most holy faith, praying in the Holy Spirit, 21 keep yourselves in the love of God, looking for the mercy of our Lord Jesus Christ unto eternal life.
