It is also to be remarked that the clothing which God provided was in itself different from what man had thought of. Adam took leaves from an inanimate, unfeeling tree; God deprived an animal of life, that the shame of His creature might be relieved. This was the last thing Adam would have thought of doing. To us life is cheap and death familiar, but Adam recognised death as the punishment of sin. Death was to early man a sign of God's anger. And he had to learn that sin could be covered not by a bunch of leaves snatched from a bush as he passed by and that would grow again next year, but only by pain and blood. Sin cannot be atoned for by any mechanical action nor without expenditure of feeling. Suffering must ever follow wrong-doing. From the first sin to the last, the track of the sinner is marked with blood. Once we have sinned we cannot regain permanent peace of conscience save through pain, and this not only pain of our own. The first hint of this was given as soon as conscience was aroused in man. It was made apparent that sin was a real and deep evil, and that by no easy and cheap process could the sinner be restored. The same lesson has been written on millions of consciences since. Men have found that their sin reaches beyond their own life and person, that it inflicts injury and involves disturbance and distress, that it changes utterly our relation to life and to God, and that we cannot rise above its consequences save by the intervention of God Himself, by an intervention which tells us of the sorrow He suffers on our account.
