'Fully' in the Bible

I rejoice because in everything I am fully confident in you.

When I was with you and was in need, I was not a burden to anyone, for the brothers who came from Macedonia fully supplied my needs. I kept myself from being a burden to you in any way, and will continue to do so.

For we rejoice whenever we are weak, but you are strong. And we pray for this: that you may become fully qualified.
