Jude 1:20
But you, dear friends, by building yourselves up in your most holy faith and praying in the Holy Spirit — Jude addresses the faithful community with encouragement, exhorting them to 'build yourselves up' (epoikodomeuntes, 'building a foundation') through engagement with the apostolic faith, which is characterized as 'most holy' (hagiotate, superlative of 'set apart for God'). Prayer 'in the Holy Spirit' (en pneumati hagio) suggests that the Spirit-empowered prayer of the faithful stands in sharp contrast to the false teachers' reliance on dreams and carnal instincts. This verse begins the hortatory climax, moving from judgment of the apostate to strengthening of the faithful.
