We don't have a "free" will. Our wills are corrupt and none of us seek after God. This isn't like the animals since they do not rebel against God willfully.
God redeems us to make us to follow in His footsteps and obey His ordiances. We're not perfect (far from it)-just redeemed.
Haha! You just proved my point. We are not just like animals, BECAUSE we have a free will. otherwise we would just be robots or instainct driven like animals.
