'Freedom' in the Bible

Were you a slave when you were called? Do not worry about that [since your status as a believer is equal to that of a freeborn believer]; but if you are able to gain your freedom, do that.

For this perishable [part of us] must put on the imperishable [nature], and this mortal [part of us that is capable of dying] must put on immortality [which is freedom from death].

And when this perishable puts on the imperishable, and this mortal puts on immortality, then the Scripture will be fulfilled that says, “Death is swallowed up in victory (vanquished forever).
