'Full' in the Bible

and those who use the world, as though they did not make full use of it; for the form of this world is passing away.

But if any man thinks that he is acting unbecomingly toward his virgin daughter, if she is past her youth, and if it must be so, let him do what he wishes, he does not sin; let her marry.

What then is my reward? That, when I preach the gospel, I may offer the gospel without charge, so as not to make full use of my right in the gospel.
