Rejoice with them that do rejoice, and weep with them that weep.
This is the practical example of the truth of Christ’s body being one. We are all members of His body, if we have been washed in His precious blood. And as members together we should have equal care for all the other members. What kind of parent would I be if I fussed over one of my children who was sick, but I ignored another one when he or she got sick? No, Christians should share in the joys and sorrows of others. This is real, practical Christianity.
