'Sufficiency' in the Bible
Not that we are sufficient of ourselves to think any thing as of ourselves; but our sufficiency is of God;
And God is able to make all grace abound toward you; that ye, always having all sufficiency in all things, may abound to every good work:
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.]
But godliness actually is a source of great gain when accompanied by contentment [that contentment which comes from a sense of inner confidence based on the sufficiency of God].
