Genesis 1:11

Let the earth bring forth grass. — This is the second creative act. The first was the calling of matter into existence, which, by the operation of mechanical and chemical laws, imposed upon it by the Creator, was arranged and digested into a cosmos, that is, an orderly and harmonious whole. These laws are now and ever in perpetual activity, but no secondary or derived agency can either add one atom to the world-mass or diminish aught from it. The second creative act was the introduction of life, first vegetable, and then animal; and for this nothing less than an Almighty power would suffice. Three stages of it are enumerated. The first is deshe, not “grass,” but a mere greenness, without visible seed or stalk, such as to this day may be seen upon the surface of rocks, and which, when examined by the microscope, is found to consist of a growth of plants of a minute and mean type. But all endogenous plants belong to this class, and are but the development of this primary greenness. Far higher in the scale are the seed-bearing plants which follow, among which the most important are the cerealia; while in the third class, vegetation reaches its highest development in the tree with woody stem, and the seed enclosed in an edible covering. Geologists inform us that cryptogamous plants, which were the higher forms of the first class, prevailed almost exclusively till the end of the carbonaceous period; but even independently of this evidence we could scarcely suppose that fruit-trees came into existence before the sun shone upon the earth; while the cerealia are found only in surface deposits in connection with vestiges of man. Vegetation, therefore, did not reach its perfection until the sixth day, when animals were created which needed these seeds and fruits for their food. But so far from there being anything in the creative record to require us to believe that the development of vegetation was not gradual, it is absolutely described as being so; and with that first streak of green God gave also the law of vegetation, and under His fostering hand all in due time came to pass which that first bestowal of vegetable life contained. It is the constant rule of Holy Scripture to include in a narrative the ultimate as well as the immediate results of an act; and moreover, in the record of these creative days we are told what on each day was new, while the continuance of all that preceded is understood. The dry land called into existence on the third day was not dry enough to be the abode of terrestrial animals till the sixth day, and not till then would it bear such vegetation as requires a dry soil; and the evidence of geology shows that the atmosphere, created on the second day. was not sufficiently free from carbonic acid and other vapours to be fit for animals to breathe, until long ages of rank vegetation had changed these gases into coal. When, then, on the third day, “God said, Let the earth bring forth grass... herb yielding seed... tree.” He gave the perfect command, but the complete fulfilment of that command would be gradual, as the state of the earth and the necessities of the living creatures brought forth upon it required. For in God’s work there is always a fitness, and nothing with Him is hurried or premature.
