No one likes to have an uninvited visitor barge in on a special occasion. An intruder interrupts and can change the tone of the occasion, whether it is a wedding, a dinner party, or some other celebration. We invite those who, by their presence, will contribute to as well as genuinely appreciate the occasion.
How true this is, especially when the occasion is healing. Christ Jesus chose carefully those whom he took with him when he was called on to heal. In the healing of Jairus's daughter See Mark 5:22-24, 35-42. there were many present, but Jesus had them all leave and took with him only Peter, James, and John, and the parents of the girl. The presence of these individuals did not interfere with or intrude on his healing work. They were ready to witness the healing of the child, and did.
What was it about the quality of their thought that enabled them to be Jesus' invited guests? Those whom he asked to leave had "laughed him to scorn" when he declared that the girl was not dead. Those who were unreceptive and doubting— even cynical—thus opposing the healing, were not invited or welcome. We read in Matthew that in his own hometown "he did not many mighty works there because of their unbelief." Matt. 13:58.
