The works of God declare his glory, but not his will. We could never learn, by studying the stars, the flowers, or the rocks, how we ought to live, what is right, and what is wrong. We could never learn what God himself is, what his attributes are, how he feels toward us. We may learn from his works, that he is great, wise, unchanging, good; but we could not learn that he loves us with a tender, personal affection. We could never find a gospel of salvation for lost sinners, in the works of God.
How thankful we should be for his Word, which tells us all these things! It teaches us how to live. It is a perfect law; not perfect only in that it is without flaw or mistake, but also in that it is complete as a revelation, containing all we need to know to be saved and to reach the full stature of godly men. We may turn to the law of the Lord with every question of duty, and we shall always find the right answer.
