Was Adam Stronger than Lions and Bears?

I'm working on my Genesis sermon for tomorrow night (Gen 1:14-31). In the process, I found something quite intriguing from Martin Luther (the great Reformer).

In commenting on man's dominion over the animal world, Luther asserts that in his opinion Adam in his original state (before sin) was superior to the animals even in those points where they were strong. He writes:

I am fully convinced that before Adam's sin his eyes were so sharp and clear that they surpassed those of the lynx and eagle. He was stronger than the lions and the bears, whose strength is very great; and he handled them the way we handle puppies (Martin Luther, Luther's Works, Vol 1, Lectures on Genesis Chapters 1-5), 62.

Is Luther on to something? In my opinion, it is probably an overstatement. However, one important point we can take from it is the reminder of the glory that was lost in being the image of God before the Fall. It also reminds of the supreme glory of the one who is the image of God, par excellence: the man Jesus Christ (Col 1:15). It should also wet our appetite as we who are in Christ, the image of God, are being transformed into the same image from one degree of glory to another (2 Cor 3:18).
