Lastly, we have here by implication, though not by direct statement, the Motive of the love.
Surely that, too, is contained in the words,' As I have loved you.' Christ's commandment of love is a new commandment, not so much because it is a revelation of a new duty, though it is the casting of an old duty into new prominence, as because it is not merely a revelation of an obligation, but the communication of power to fulfil it. The novelty of Christian morality lies here, that in its law there is a self-fulfilling force. We have not to look to one place for the knowledge of our duty, and somewhere else for the strength to do it, but both are given to us in the one thing, the gift of the dying Christ and His immortal love.
That love, received into our hearts, will conquer, and it alone will conquer, our selfishness. That love, received into our hearts, will mould, and it alone will mould, them into its own likeness. That love, received into our hearts, will knit, and it alone will knit, all those who participate in it into a common bond, sweet, deep, sacred, and all-victorious.
And so, brethren, if we would know the blessedness and the sweetness of victory over these miserable, selfish hearts of ours, and to walk in the liberty of love, we can only get it by keeping close to Jesus Christ. In any circle, the nearer the points of the circumference are to the centre, the closer they will necessarily be to one another. As we draw nearer, each for himself, to our Centre, we shall feel that we have approximated to all those who stand round the same centre, and draw from it the same life. In the early spring, when the wheat is green and young, and scarcely appears above the ground, it comes up in the lines in which it was sown, parted from one another and distinctly showing their separation and the furrows. But when the full corn in the ear waves on the autumn plain, all the lines and separations have disappeared, and there is one unbroken tract of sunny fruitfulness. And so when the life in Christ is low and feeble, His servants may be separated and drawn up in rigid lines of denominations, and churches, and sects; but as they grow the lines disappear. If to the churches of England to-day there came a sudden accession of knowledge of Christ, and of union with Him, the first thing that would go would be the wretched barriers that separate us from one another. For if we have the life of Christ in any adequate measure in ourselves, we shall certainly have grown up above the fences behind which we began to grow, and shall be able to reach out to all that love the Lord Jesus Christ, and feel with thankfulness that we are one in Him.
