Some friends of ours from our old church have an orginization in China called Bring Me Hope. They go to China every summer, and put on week long camps for the Chinese orphans. It is such a precious time of ministry, for both the orphans and the volunteers. The volunteers are assigned two "buddies" for the week. My friend Christoper Calvi is over there right now, and on his blog he says that he had two of the best buddies you could ask for. He also said that when the week was up, it was a very tearful goodbye. He will most likely never see his buddies again, but they have built lifelong memories together he says. God has truly moved in a mighty way through Bring Me Hope.
