Finally, be all like-minded, compassionate, loving as brothers, tenderhearted, courteous,
having compassion one of another: This compassion (sumpathees) is defined as "suffering or feeling the like with another, sympathetic" (Thayer 596-2-4835). This word, as well as the word for being of one mind, occurs only here in the New Testament. It denotes "suffering with," being sympathetic to all other people of God. With the Lord’s people, there is to be an interchange of mutual feeling for our brothers and sisters in Christ in joy or in sorrow.
