The apostle having given an account of the excellency of the renewed spiritual man as born again, not of corruptible but incorruptible seed, he now sets before us the vanity of the natural man, taking him with all his ornaments and advantages about him: For all flesh is as grass, and all the glory of man as the flower of grass; and nothing can make him a solid substantial being, but the being born again of the incorruptible seed, the word of God, which will transform him into a most excellent creature, whose glory will not fade like a flower, but shine like an angel; and this word is daily set before you in the preaching of the gospel. Learn, 1. Man, in his utmost flourish and glory, is still a withering, fading, dying creature. Take him singly, all flesh is grass. In his entrance into the world, in his life and in his fall, he is similar to grass, Job 14:2; Isa 40:6, Isa 40:7. Take him in all his glory, even this is as the flower of grass; his wit, beauty, strength, vigour, wealth, honour - these are but as the flower of grass, which soon withers and dies away. 2. The only way to render this perishing creature solid and incorruptible is for him to entertain and receive the word of God; for this remains everlasting truth, and, if received, will preserve him to everlasting life, and abide with him for ever. 3. The prophets and apostles preached the same doctrine. This word which Isaiah and others delivered in the Old Testament is the same which the apostles preached in the New.
