Of course, we have here, underlying the phrase, the familiar comparison of life to a journey, with all its suggestions of constant change and constant effort, and with the suggestion, too, that each life should be a progress directly tending to one clearly recognised goal. But passing from that, let us just think for a moment of the characteristics which must go to make up a life of which we can say that it is walking with God. The first of these clearly is the one that the writer of the Epistle to the Hebrews puts his finger upon, when he makes faith the spring of Enoch's career. The first requisite to true communion with God is vigorous exercise of that faculty by which we realise the fact of His presence with us; and that not as a jealous-eyed inspector, from whose scrutiny we would fain escape, but as a companion and friend to whom we can cleave. 'He that cometh to God,' and walks with God, must first of all 'believe that He _is_'; and passing by all the fascinations of things seen, and rising above all the temptations of things temporal, his realising eye must fix upon the divine Father and see Him nearer and more clearly than these. You cannot walk with God unless you are emancipated from the dominion of sense and time, and are living by the power of that great faculty, which lays hold of the things that are unseen as the realities, and smiles at the false and forged pretensions of material things to be the real. We have to invert the teaching of the world and of our senses. My fingers and my eyes and my ears tell me that this gross, material universe about me is the real, and that all beyond it is shadowy and (sometimes we think) doubtful, or, at any rate, dim and far off. But that is false, and the truth is precisely the other way. The Unseen is the Real, and the Material is the merely Apparent. Behind all visible objects, and giving them all their reality, lies the unchangeable God. Cultivate the faculty and habit of vigorous faith, if you would walk with God. For the world will put its bandages over your eyes, and try to tempt you to believe that these poor, shabby illusions are the precious things; and we have to shake ourselves free from its harlot kisses and its glozing lies, by very vigorous and continual efforts of the will and of the understanding, if we are to make real to ourselves that which is real, the presence of our God.
