And the same duality belongs to the life of those who are 'after the Spirit.' 'To walk,' of course, means to carry on the practical life, and the Spirit is here thought of not so much perhaps as the path on which we are to travel, but rather as the norm and direction by which we are to travel on life's common way. Just as the desires of the flesh were certain to be done by those who in their deepest selves belonged to the flesh, so every soul which has received the unspeakable gift of newness of life through the Spirit of God will have the impulses to mind and do the things of the Spirit. If we live in the Spirit we shall also--and let us also--walk in the Spirit. But let us make no mistakes, or think that our text in its great commandment and radiant hope has any word of cheer to those who have not received into their hearts, in however feeble a manner and minute a measure, the Spirit of the Son. The first question for us all is, have we received the Holy Ghost?--and the answer to that question is the answer to the other, have we accepted Christ? It is through Him and through faith in Him that that supreme gift of a living spirit is bestowed. And only when our spirits bear witness with that Spirit that we are the children of God, have we a right to look upon the text as pointing our duty and stimulating our hope. If our practical life is to be directed by the Spirit of God, He must enter into our spirits, and we shall not be in Him but in the measure that He is in us. Nor will our spirits be life because of righteousness unless He dwells in us and casts forth the works of the flesh. There will be no practical direction of our lives by the Spirit of God unless we make conscience of cultivating the reception of His life-giving and cleansing influences, and unless we have inward communion with our inward guide, intimate and frank, prolonged and submissive. If we are for ever allowing the light of our inward godliness to be blown about by gusts, or to show in our inmost hearts but a faint and flickering spark, how can we expect that it will shine safe direction on our outward path? II. Such walking in the Spirit conquers the flesh.
