Observe you everything that takes place in the heaven, how they do not change their orbits, and the luminaries which are in the heaven, how they all rise and set in order each in its season, and transgress not against their appointed order. Behold you the earth, and give heed to the things which take place upon it from first to last, how steadfast they are, how none of the things upon earth change, but all the works of God appear to you. Behold the summer and the winter, how the whole earth is filled with water, and clouds and dew and rain lie upon it. Observe and see how ( in the winter ) all the trees seem as though they had withered and shed all their leaves, except fourteen trees, which do not lose their foliage but retain the old foliage from two to three years till the new comes. And again, observe you the day of summer how the sun is above the earth over against it. And you seek shade and shelter by reason of the heat of the sun, and the earth also burns with glowing heat, and so you can not tread on the earth, or on a rock by reason of its heat. Observe you how the trees cover themselves with green leaves and bear fruit: Wherefore give you heed and know with regard to all His works, and recognize how He that lives for ever hath made them so. And all His works go on thus from year to year for ever, and all the tasks which they accomplish for Him, and their tasks change not, but according as God hath ordained so is it done. And behold how the sea and the rivers in like manner accomplish and change not their tasks from His commandments’. The only thing that has not and does not keep God’s commandments is US.
