I understand the allegory but always figured a God who could create an animal would have better things to do than go hunting, kill an animal, gut it, skin it, deflesh the hide, tan it, stretch it to dry over a smoky fire, and then soften it, cut it to size, stitch it into a garment and then give the clothes to Adam and Eve.
Seems like it would be more practical for the Creator to just create what he has in mind, like He did with light. Adam and Eve could then reverses engineer the process from studying what they had.
No, blood had to be shed to “clothe” Adam and Eve properly after they sinned. In God’s eyes, their need for the spiritual clothing of God’s righteousness and redemption was inseparable from their need for physical clothes. The Bible shows us that everything God did and does with man points to Jesus, and until Jesus’ death on the cross, the blood of animals served as a temporary substitute for Jesus Christ himself, the Lamb of God.
