(_b_) True Christians are called "a family," because they all _rejoice in one name_. That name is the name of their great Head and Elder Brother, even Jesus Christ the Lord. Just as a common family name is the uniting link to all the members of a Highland clan, so does the name of Jesus tie all believers together in one vast family. As members of outward visible Churches they have various names and distinguishing appellations. As living members of Christ, they all, with one heart and mind, rejoice in one Saviour. Not a heart among them but feels drawn to Jesus as the only object of hope. Not a tongue among them but would tell you that "Christ is all." Sweet to them all is the thought of Christ's death for them on the cross. Sweet is the thought of Christ's intercession for them at the right hand of God. Sweet is the thought of Christ's coming again to unite them to Himself in one glorified company for ever. In fact, you might as well take away the sun out of heaven, as take away the name of Christ from believers. To the world there may seem little in His name. To believers it is full of comfort, hope, joy, rest, and peace. No wonder they are called "a family." (_c_) True Christians, above all, are called "a family" because there is so strong _a family likeness_ among them. They are all led by one Spirit, and are marked by the same general features of life, heart, taste, and character. Just as there is a general bodily resemblance among the brothers and sisters of a family, so there is a general spiritual resemblance among all the sons and daughters of the Lord Almighty. They all hate sin and love God. They all rest their hope of salvation on Christ, and have no confidence in themselves. They all endeavour to "come out and be separate" from the ways of the world, and to set their affections on things above. They all turn naturally to the same Bible, as the only food of their souls and the only sure guide in their pilgrimage toward heaven: they find it a "lamp to their feet, and a light to their path." (Psa. cxix. 105.) They all go to the same throne of grace in prayer, and find it as needful to speak to God as to breathe. They all live by the same rule, the Word of God, and strive to conform their daily life to its precepts. They have all the same inward experience. Repentance, faith, hope, charity, humility, inward conflict, are things with which they are all more or less acquainted. No wonder they are called "a family."
