What does the Bible say about the significance of Adam and Eve's clothing?

In Genesis 3:21, God made coats of skins and clothed Adam and Eve, representing that their own efforts to cover their nakedness with fig leaves were insufficient. This act underscores the truth that man-made solutions cannot justify or reconcile us before a holy God. The coats of skins symbolize the need for a covering that can only be provided by God, pointing to the ultimate sacrifice of Christ. Without the shedding of blood, there is no remission of sins, indicating that the means by which we can stand before God includes atonement through Christ's sacrifice.
