'Have Faith' in the Bible

But we are not like those people who turn back and are destroyed, but like those who have faith [in God] and obtain the salvation of their souls.

These people [all] continued to have faith until they died, [even though] they had not obtained [all] the things God had promised, but had [only] seen them and welcomed them from a distance. And they had confessed to being strangers and aliens on earth.
