'Sufficiency' in the Bible

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.

I can do all things [which He has called me to do] through Him who strengthens and empowers me [to fulfill His purpose—I am self-sufficient in Christ’s sufficiency; I am ready for anything and equal to anything through Him who infuses me with inner strength and confident peace.]
