'Confident' in the Bible

I wrote this very thing so that when I came I wouldn’t have pain from those who ought to give me joy, because I am confident about all of you that my joy will also be yours.

So, we are always confident and know that while we are at home in the body we are away from the Lord.

and we are confident and satisfied to be out of the body and at home with the Lord.

Look at what is obvious. If anyone is confident that he belongs to Christ, he should remind himself of this: Just as he belongs to Christ, so do we.

Since I am confident of your obedience, I am writing to you, knowing that you will do even more than I say.

Even though we are speaking this way, dear friends, in your case we are confident of the better things connected with salvation.
