“The meanest and most contemptible person whom we behold is the offspring of heaven, one of the children of the Most High; and, however unworthily he may behave, so long as God hath not passed on him a final sentence, He will have us acknowledge him as one of His; and, as such, to embrace him with a sincere and cordial affection.”
