From man is the seed, that once cast into the womb man hath no more to do with it. Another cause succeedeth, and undertakes the work, and in time brings a child (that wonderful effect from such a beginning!) to perfection. Again, man lets food down through his throat; and that once down, he hath no more to do with it. Another cause succeedeth and distributeth this food into the senses, and the affections: into life, and into strength; and doth with it those other many and marvellous things, that belong unto man. These things therefore that are so secretly and invisibly wrought and brought to pass, thou must use to behold and contemplate; and not the things themselves only, but the power also by which they are effected; that thou mayst behold it, though not with the eyes of the body, yet as plainly and visibly as thou canst see and discern the outward efficient cause of the depression and elevation of anything.
