2. The word of our God, that glory of the Lord which is now to be revealed, the gospel, and that grace which is brought with it to us and wrought by it in us, shall stand for ever; and this is the satisfaction of all believers, when they find all their creature-comforts withering and fading like grass. Thus the apostle applies it to the word which by the gospel is preached unto us, and which lives and abides for ever as the incorruptible seed by which we are born again, 1 Pet. i. 23-25. To prepare the way of the Lord we must be convinced, (1.) Of the vanity of the creature, that all flesh is grass, weak and withering. We ourselves are so, and therefore cannot save ourselves; all our friends are so, and therefore are unable to save us. All the beauty of the creature, which might render it amiable, is but as the flower of grass, soon blasted, and therefore cannot recommend us to God and to his acceptance. We are dying creatures; all our comforts in this word are dying comforts, and therefore cannot be the felicity of our immortal souls. We must look further for a salvation, look further for a portion. (2.) Of the validity of the promise of God. We must be convinced that the word of the Lord can do that for us which all flesh cannot—that, forasmuch as it stands for ever, it will furnish us with a happiness that will run parallel with the duration of our souls, which must live for ever; for the things that are not seen, but must be believed, are eternal.
