'Lost' in the Bible

To God we are the aroma of the Messiah among those who are being saved and among those who are being lost.

In fact, that which once had glory lost its glory, because the other glory surpassed it.

But [in fact] their minds were hardened [for they had lost the ability to understand]; for until this very day at the reading of the old covenant the same veil remains unlifted, because it is removed [only] in Christ.

But if our gospel be hid, it is hid to them that are lost:

I repeat then, let no one think that I am foolish; but even if you do, at least accept me as foolish, so that I too may boast a little.
