Since the beginning, God had always made plans for us that we might not perish before his just wrath. When Adam and Eve sinned before the Lord, and covered themselves with fig leaves, God made a garments of skins and clothed them.
When Abraham was asked of God to take his only son and offer himself up, God makes a provision there and gives a ram instead. When the terrible plague was to descend upon the people of Egypt, God makes a provision that any house which has an unblemished lamb’s blood smeared on it’s door post will not be touched.
Other provisions of God include a city of refuge so that the murderers can go and wait for a reasonable trial. And for some there existed a blessing, “Blessed is a man to whom the Lord imputes not iniquity, and in whose spirit there is no guile.”
These were all an imagery of Christ.
