'Self-sufficient' in the Bible

Even though he is satiated and self-sufficient, he suffers everyone in any sort of trouble will attack him.

And God is able to make all grace (every favor and earthly blessing) come to you in abundance, so that you may always and under all circumstances and whatever the need be self-sufficient [possessing enough to require no aid or support and furnished in abundance for every good work and charitable donation].

I have strength for all things in Christ Who empowers me [I am ready for anything and equal to anything through Him Who infuses inner strength into me; I am self-sufficient in Christ's sufficiency].
