'Straitened' in the Bible

But small is the gate and narrow and difficult to travel is the path that leads the way to [everlasting] life, and there are few who find it.

I know how to get along and live humbly [in difficult times], and I also know how to enjoy abundance and live in prosperity. In any and every circumstance I have learned the secret [of facing life], whether well-fed or going hungry, whether having an abundance or being in need.
