Passage
And if they had called to mind that from whence they went out, they had had opportunity to have returned;
And if they had called to mind that from whence they went out, they had had opportunity to have returned;
Hebrews 11:13 All these died in faith, not having received the promises, but having seen them from afar off and embraced [them], and confessed that they were strangers and sojourners on the earth.
Hebrews 11:14 For they who say such things shew clearly that they seek [their] country.
Hebrews 11:15 And if they had called to mind that from whence they went out, they had had opportunity to have returned;
Hebrews 11:16 but now they seek a better, that is, a heavenly; wherefore God is not ashamed of them, to be called their God; for he has prepared for them a city.
Hebrews 11:17 By faith Abraham, [when] tried, offered up Isaac, and he who had received to himself the promises offered up his only begotten [son],
The verse centers on "called", "mind", "whence", "went", "opportunity", and "returned". It is saying that the verse draws attention to "called" and "mind", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 14's "For they who say such things shew..." into verse 16's "but now they seek a better that...", so "called" and "mind" belong inside that flow. In Hebrews context, the local focus is Christ, faith, and discipleship.
A plain takeaway is to answer the verse's own emphasis on "called" and "mind" with trust shaped by these words, not by a vague optimism outside the passage.
