That is a sweet, simple, easily intelligible, and yet lofty way of putting the notion which we bring into a more abstract and less impressive shape when we talk about communion with God. Two men travelling along a road keep each other company. 'How can two walk together except they be agreed?' The companion is at our side all the same, though the mists may have come down and we cannot see Him. We can hear His voice, we can grasp His hand, we can catch the echoes of His steps. We know He is there, and that is enough. Enoch and God walked together, by the simple exercise of the faith that fills the Invisible with one great, loving Face. By a continuous, definite effort, as we are going through the bustle of daily life, and amid all the pettiness and perplexities and monotonies that make up our often weary and always heavy days, we can realise to ourselves that He is of a truth at our sides, and by purity of life and heart we can bring Him nearer, and can make ourselves more conscious of His nearness. For, brethren, the one thing that parts a man from God, and makes it impossible for a heart to expatiate in the thought of His presence, is the contrariety to His will in our conduct. The slightest invisible film of mist that comes across the blue abyss of the mighty sky will blot out the brightest of the stars, and we may sometimes not be able to see the mist, and only know that it is there because we do not see the planet. So unconscious sin may steal in between us and God, and we shall no longer be able to say, 'I walk with Him.' The Roman Catholics talk, in their mechanical way, of bringing down all the spiritual into the material and formal, about the 'practice of the presence of God.' It is an ugly phrase, but it means a great thing, that Christian people ought, very much more than they do, to aim, day by day, and amidst their daily duties, at realising that most elementary thought which, like a great many other elementary thoughts, is impotent because we believe it so utterly, that wherever we are, we may have Him with us. It is the secret of blessedness, of tranquillity, of power, of everything good and noble.
