Reacting to the joy and sorrow of others; dealing with envy; having the same mind; avoiding intellectual pride and ambition; being carried along with humble things and people.
Practical Christianity (2) – Dr. Martyn Lloyd-Jones Sermon
Romans 12:15 Rejoice with those who rejoice; mourn with those who mourn. 16 Live in harmony with one another. Do not be proud, but be willing to associate with people of low position. Do not be conceited.
