We must carefully observe that these great words of our Lord are not intended to describe the means by which men become His kinsfolk, but the tokens that they are such. He is not saying--as superficial readers sometimes run away with the notion that He is saying--'If a man will, apart from Me, do the will of God, then he will become My true kinsman,' but He is saying, 'If you are My kinsman, you will do the will of God, and if you do it, you will show that you are related to Myself.' In other words, He is not speaking about the means of originating this relationship, but about the signs of its reality. And, therefore, the words of my text need, for their full understanding, and for placing them in due relation to all the rest of Christ's teaching, to be laid side by side with other words of His, such as these:--'Apart from Me ye can do nothing.' For the deepest truth in regard to relationship to Jesus Christ and obedience is this, that the way by which men are made able to do the will of God is by receiving into themselves the very life-blood of Jesus Christ. The relationship must precede the obedience, and the obedience is the sign, because it is the sequel, of the relationship. But far deeper down than mere affinity lies the true bond between us and Christ, and the true means of performing the commandments of God. There must be a passing over into us of His own life-spirit. By His inhabiting our hearts, and moulding our wills, and being the life of our lives and the soul of our souls, are we made able to do the commandments of the Lord. And so, seeing that actual union with Jesus Christ, and the reception into ourselves of His life, is the precedent condition of all true obedience, then the more familiar form of presenting the bond between Him and us, which runs through the New Testament, falls into its proper place, and the faith, which is the condition of receiving the life of Christ into our hearts, is at once the affinity which makes us His kindred, and the means by which we appropriate to ourselves the power of obedient submission and conformity to the will of God. 'This is the work of God, that ye believe on Him whom He hath sent.' So, then, my text does not in the slightest degree contradict or interfere with the great teaching that the one way by which we become Christ's brethren is by trusting in Him. For the text and the doctrine that faith unites us to Him take up the process at different stages: the one pointing to the means of origination, the other to the tokens of reality. Faith is the root, obedience is the flower and the fruit. He that doeth the will of God, does it, not in order that he may become, but because he already is, possessor of a blood-relationship to Jesus Christ.
