Observe, moreover, the emphasis on _doing_, with which we are already familiar. In setting forth the Gospel of the Kingdom, our Lord was careful to warn His hearers: "Not every one that saith unto Me, Lord, Lord, shall enter into the kingdom of heaven; but he that doeth the will of My Father" (vii. 21); and now that He is setting forth the Gospel of the Family the emphasis is still in the same place. It is not "Whosoever shall connect himself with this church or that church;" it is not "Whosoever shall be baptised, and take the sacrament;" it is "Whosoever shall do the will of My Father in heaven." This emphasis on doing, in connection with these endearing relations, is most significant. There must be love among the members of the family; and what else than love is the characteristic of the family ties? But how is love to be shown? How are we to distinguish it from mere sentiment? Our Saviour is careful to teach us; and never is He more careful than in those passages where tender feeling is most prominent--as, for example, in His parting words in the upper room, where again and again He reminds His disciples that obedience is the only sure test of love: "If ye love Me, keep My commandments;" "He that hath My commandments, and keepeth them, he it is that loveth Me" (John xiv. 15, 21). For the same reason obedience is here set forth as the only certain mark of the true disciple: "Whosoever shall do the will of My Father which is in heaven, the same is My brother, and sister, and mother." [10] This is the literal translation, which means more than "give you rest." It is not as if rest were a blessing He could bestow, as a friend would make a present which might be retained after the giver had gone. Rest is not so much what He gives to us as what He is to us; and so He says, not "I will give you rest," but "I will rest you" (_i.e._, I will _be_ your rest). [11] "The Service of Man," by J.
