Passage
Let us therefore fear, lest, a promise being left of entering into his rest, any one of you might seem to have failed [of it].
Let us therefore fear, lest, a promise being left of entering into his rest, any one of you might seem to have failed [of it].
Hebrews 4:1 Let us therefore fear, lest, a promise being left of entering into his rest, any one of you might seem to have failed [of it].
Hebrews 4:2 For indeed we have had glad tidings presented to us, even as they also; but the word of the report did not profit *them*, not being mixed with faith in those who heard.
Hebrews 4:3 For we enter into the rest who have believed; as he said, As I have sworn in my wrath, If they shall enter into my rest; although the works had been completed from [the] foundation of [the] world.
The verse centers on "therefore", "fear", "lest", "promise", "left", "entering", "rest", and "might". It is saying that the verse draws attention to "therefore" and "fear", so its meaning should be read from those terms before moving to application.
The next verse adds "For indeed we have had glad tidings...", so "therefore" and "fear" should be read forward into that movement. In Hebrews context, the local focus is Christ, faith, and discipleship.
A plain takeaway is to answer the verse's own emphasis on "therefore" and "fear" with trust shaped by these words, not by a vague optimism outside the passage.
