'Confident' in the Bible

Therefore we are always confident, knowing that, whilst we are at home in the body, we are absent from the Lord:

We are confident, I say, and willing rather to be absent from the body, and to be present with the Lord.

Lest haply if they of Macedonia come with me, and find you unprepared, we (that we say not, ye) should be ashamed in this same confident boasting.
