Remember, too, that the impartation of this highest good is one of the main reasons why we ourselves possess it. Jesus Christ can redeem the world alone, but it cannot become a redeemed world without the help of His servants. He needs us in order to carry into all humanity the energies that He brought into the midst of mankind by His Incarnation and Sacrifice; and the cradle of Bethlehem and the Cross of Cavalry are not sufficient for the accomplishment of the purpose for which they respectively came to pass, without the intervention and ministry of Christian people. It was for this end amongst others, that each of us who have received that great gift into our hearts have been enriched by it. The river is fed from the fountains of the hills, in order that it may carry verdure and life whithersoever it goes. And you and I have been brought to the Cross of Christ, and made His disciples, not only in order that we ourselves might be blessed and quickened by the gift unspeakable, but in order that through us it may be communicated, just as each particle when leavened in the mass of the dough communicates its energy to its adjacent particle until the whole is leavened. I am afraid that indifference to the communication of the highest good, which marks sadly too many Christian professors in all ages, and in this age, is a suspicious indication of a very slight realisation of the good for themselves. Luther said that justification was the article of a standing or a falling church. That may be true in the region of theology, but in the region of practical life I do not know that you will find a test more reliable and more easy of application than this, Does a man care for spreading amongst his fellows the gospel that he himself has received? If he does not, let him ask himself whether, in any real sense, he has it. 'Well-doing' includes doing good to others, and the possession of Christ will make it certain that we shall impart Him. II. Notice the bearing of this elementary injunction upon the scope of the obligation.
