Romans 12:15

Rejoice with them that rejoice; weep with them that weep.

This teaches the community of mankind. The Christian does not exist in a state of isolation and indifference to the fate of others, but, like his holy Master, has compassion, being involved in and moved by the emotions of others, whether of joy or sorrow. Only the wicked or the thoughtless are callused against the joys and sorrows of humanity; and, if one permits himself to become hardened against concern for fellow mortals, he thereby forfeits the likeness he might have had for him who wept at the grave of Lazarus, had compassion on the multitude, and replenished the wine at the wedding in Cana.
