The Old Law is a preparation for the Gospel. "The Law is a pedagogy and a prophecy of things to come." 17 It prophesies and presages the work of liberation from Sin which will be Fulfilled in Christ: it provides the New Testament with Images, "types," and symbols for Expressing the life according to the Spirit. Finally, the Law is completed by the teaching of the sapiential books and the Prophets which set its course Toward the New Covenant and the Kingdom of heaven.
