James Macdonald said this quote

When it comes to biblical counseling, friendship is central to the counseling relationship because it is a key aspect of the Gospel. Paul's words display it; Jesus' actions approve it. In Jesus Christ, friendship has its ultimate – that is, it's paradigmatic – display. He sacrificially gave Himself for the good of those he befriended – people who were awkward and troubled types, people who did not offer Him anything particularly desirable in return.
