'Lose' in the Bible

For whoever wants to save his life will lose it, but whoever loses his life because of Me and the gospel will save it.

For what does it benefit a man to gain the whole world yet lose his life?

And whoever gives you a cup of water to drink because of My name, since you belong to the Messiah—I assure you: He will never lose his reward.

Salt is good, but if the salt should lose its flavor, how can you make it salty? Have salt among yourselves and be at peace with one another.”
