What the Law Foreshadowed

Why did the LORD use shadows and types in the Old Testament to proclaim the coming of His Son Jesus Christ in the flesh as the Redeemer of His chosen ones? How is the LORD Jesus Christ the fulfillment of all the law of the Old Testament? How does the Holy Spirit reveal this Christ to His redeemed? Why does the LORD blind the hearts of some? Who is it that revealed to Peter that Jesus was the Christ that was promised by God? How is the Tabernacle of the Old Testament typify Christ? Why couldn't the animal sacrifices of the Old Testament put away sin? How did the animal sacrifices foreshadow true salvation in Christ? Why did Christ come in a body of a man but without sin? Is the entire Bible, both Old and New Testaments about Jesus Christ and His fulfillment as God's redemptive will?
