Jude 21 keep yourselves in the love of God, looking for the mercy of our Lord Jesus Christ unto eternal life.
Jude appeals to Christians to remain in God’s love; we are to abide in Christ, and by doing so, He will abide in us, John 15:4. The idea is to remain steadfast in God’s love. But what does this mean?
Jude 20 But you, beloved, building yourselves up on your most holy faith, praying in the Holy Spirit,
Jude diverts the reader’s attention from the false teachers that have thus far been the object of his epistle to themselves. Jude tells his fellow Christians to build themselves up on their faith. The idea here implies that we are, as God’s saints, to build upon the foundation of our faith, which is Jesus Christ, 1 Corinthians 3:11.
Jude 19 These are sensual persons, who cause divisions, not having the Spirit.
This verse is the final direct conversation Jude has about these false teachers, though he will allude to them again toward the conclusion of his epistle. In this verse we learn three more things about the false teachers. In an effort to bring us into this culmination, we should recapitulate what Jude has already said about these men.
Jude 18 how they told you that there would be mockers in the last time who would walk according to their own ungodly lusts.
I don’t typically begin the conversation with a biblical quote, but it is appropriate to cite 1 Timothy 4:1: “Now the Spirit expressly says that in latter times some will depart from the faith, giving heed to deceiving spirits and doctrines of demons.” The apostles of the Lord warned that we should adhere to the words they have committed by virtue of the Holy Spirit’s inspiration, Jude 17. Why? Because the same Holy Spirit warns the church that in later times professing Christians will leave behind the truth, paying attention to, and being deceived by, the doctrines of demons. The saint is not to, “give place to the devil,” Ephesians 4:27; that is, not to give him a foothold in our lives by which he may lead us from our faith whichever distraction most pleases us.
Jude 17 But you, beloved, remember the words which were spoken before by the apostles of our Lord Jesus Christ:
Jude reminds us (and his readership) that if we are fellow Christians, we are beloved. We are not only beloved by Jude, but we are to love and be loved by anyone who names Jesus Christ as their Savior. Jesus told us, “A new commandment I give to you, that you love one another; as I have loved you, that you also love one another. By this all will know that you are My disciples, if you have love for one another,” John 13:34, 35.
