Passage
But you, beloved, building yourselves up on your most holy faith, praying in the Holy Spirit,
But you, beloved, building yourselves up on your most holy faith, praying in the Holy Spirit,
Jude 1:18 that they were saying to you, “In the last time there will be mockers, following after their own ungodly lusts.”
Jude 1:19 These are the ones who cause divisions, worldly-minded, not having the Spirit.
Jude 1:20 But you, beloved, building yourselves up on your most holy faith, praying in the Holy Spirit,
Jude 1:21 keep yourselves in the love of God, waiting for the mercy of our Lord Jesus Christ to eternal life.
Jude 1:22 And on some, who are doubting, have mercy;
The verse centers on "Spirit", "faith", "beloved", "building", "yourselves", "most", "holy", and "praying". It is saying that the verse draws attention to "Spirit" and "faith", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 19's "These are the ones who cause divisions..." into verse 21's "keep yourselves in the love of God...", so "Spirit" and "faith" belong inside that flow. In Jude context, the local focus is Christ, faith, and discipleship.
A plain takeaway is to answer the verse's own emphasis on "Spirit" and "faith" with trust shaped by these words, not by a vague optimism outside the passage.
