We might think it is demeaning to refer to oneself as a slave or a servant, but in the first century, the slave of a high-ranking official often had more influence and authority than the average free Roman citizen. A servant sent in the name of his master came with conferred authority; therefore, to rebuff the servant was to rebuff the one who sent him. As the servants of Jesus Christ, we have been sent in His name, and there is power in the name of Jesus.
