God's family on earth

Having done a little travelling over the last few days, I should like to attest once more to the following:
How glorious is the thought that there is a family even upon earth of which the Son of God holds Himself a part; a family, the loving bond and reigning principle of which is subjection to the Father of our Lord Jesus Christ, and so embracing high and low, rude and refined, bond and free, of every kindred and every age that have tasted that the Lord is gracious; a family whose members can at once understand each other and take sweetest counsel together, though meeting for the first time from the ends of the earth - while with their nearest relatives, who are but the children of this world, they have no sympathy in such things; a family which death cannot break up, but only transfer to their Father's house! Did Christians but habitually realize and act upon this, as did their blessed Master, what would be the effect upon the Church and upon the world?
