A.T. Robertson Commentary Revelation 14:12

"Here is the patience of the saints, they that keep the commandments of God, and the faith of Jesus." — Revelation 14:12 (ASV)

Here is the patience of the saints (Hωδε η υπομονη των αγιων εστιν). John's own comment as in 13:10; 17:9. In this struggle against emperor worship lay their opportunity (Romans 5:3). It was a test of loyalty to Christ.

They that keep (ο τηρουντες). In apposition with των αγιων (genitive), though nominative, a frequent anacoluthon in this book (2:20, etc.). Cf. 12:17.

The faith of Jesus (την πιστιν Ιησου). "The faith in Jesus" (objective genitive) as in 2:13; Mr 11:22; James 2:1.
