Under the curse of sin all nature was to witness to man of the character and results of rebellion against God. When God made man He made him rule over the earth and all living creatures. So long as Adam remained loyal to Heaven, all nature was in subjection to him. But when he rebelled against the divine law, the inferior creatures were in rebellion against his rule. Thus the Lord, in His great mercy, would show men the sacredness of His law, and lead them, by their own experience, to see the danger of setting it aside, even in the slightest degree.
And the life of toil and care which was henceforth to be man’s lot was appointed in love. It was a discipline rendered needful by his sin, to place a check upon the indulgence of appetite and passion, to develop habits of self-control. It was a part of God’s great plan of man’s recovery from the ruin and degradation of sin.
