Adam and Eve Were Promised Redemption

The fall of Adam and Eve established the need for redemption and the Redeemer.
God illustrated the means of redemption: He sacrificed an animal and shed its blood. Then, God took the skins of the animal and covered the pair, which foreshadowed the imputation of righteousness. By this, God promised the Lamb of God, Jesus Christ, as seen in person and declared by John the Baptist.
