'Losing' in the Bible

Anyone finding his life will lose it, and anyone losing his life because of Me will find it.

"What man of you, having a hundred sheep and losing one of them, does not leave the ninety-nine in the grassland and go after the one that was lost until he finds it?

But if any person’s work is burned up [by the test], he will suffer the loss [of his reward]; yet he himself will be saved, but only as [one who has barely escaped] through fire.

He must manage his own household well and keep his children in control without losing his dignity.

Just consider and meditate on Him who endured from sinners such bitter hostility against Himself [consider it all in comparison with your trials], so that you will not grow weary and lose heart.
