Passage
Be watchful, and strengthen the things that remain, which are about to die, for I have not found thy works complete before my God.
Be watchful, and strengthen the things that remain, which are about to die, for I have not found thy works complete before my God.
Revelation 3:1 And to the angel of the assembly in Sardis write: These things saith he that has the seven Spirits of God, and the seven stars: I know thy works, that thou hast a name that thou livest, and art dead.
Revelation 3:2 Be watchful, and strengthen the things that remain, which are about to die, for I have not found thy works complete before my God.
Revelation 3:3 Remember therefore how thou hast received and heard, and keep [it] and repent. If therefore thou shalt not watch, I will come [upon thee] as a thief, and thou shalt not know at what hour I shall come upon thee.
Revelation 3:4 But thou hast a few names in Sardis which have not defiled their garments, and they shall walk with me in white, because they are worthy.
The verse centers on "watchful", "strengthen", "things", "remain", "found", "works", "complete", and "before". It is saying that the verse draws attention to "watchful" and "strengthen", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 1's "And to the angel of the assembly..." into verse 3's "Remember therefore how thou hast received and...", so "watchful" and "strengthen" belong inside that flow. In Revelation context, the local focus is Christ, faith, and discipleship.
A plain takeaway is to answer the verse's own emphasis on "watchful" and "strengthen" with trust shaped by these words, not by a vague optimism outside the passage.
