'Anyone' in the Bible

Therefore if anyone is in Christ, he is a new creation. The old things have passed away. Behold, all things have become new.

Do you look at things only as they appear in front of your face? If anyone trusts in himself that he is Christ's, let him consider this again with himself, that, even as he is Christ's, so also we are Christ's.

When I was present with you and was in need, I wasn't a burden on anyone, for the brothers, when they came from Macedonia, supplied the measure of my need. In everything I kept myself from being burdensome to you, and I will continue to do so.

Did I take advantage of you by anyone of them whom I have sent to you?
