Galatians 4:17-20

They zealously affect you, but not well; yea, they would exclude you, that ye might affect them. But it is good to be zealously affected always in a good thing, and not only when I am present with you. My little children, of whom I travail in birth again until Christ be formed in you, I desire to be present with you now, and to change my voice; for I stand in doubt of you.
