Discussing Christ as the end of the law in his preface to Pierre-Robert Olivetan’s translation of the New Testament, Calvin writes:

“Therefore, when you hear that the gospel presents you Jesus Christ in whom all the promises and gifts of God have been accomplished; and when it declares that he was sent by the Father, has descended to the earth and spoken among men perfectly all that concerns our salvation, as it was foretold in the Law and to the Prophets – it ought to be most certain and obvious to you that the treasures of Paradise have been opened to you in the gospel; that the riches of God have been exhibited and eternal life itself revealed. For, this is eternal life; to know one, only true God, and Jesus Christ whom he has sent, whom he has established as the beginning, the middle, and the end of our salvation. He [Christ] is Isaac, the beloved Son of the Father who was offered as a sacrifice, but nevertheless did not succumb to the power of death. He is Jacob the watchful shepherd, who has such great care for the sheep which he guards. He is the good and compassionate brother Joseph, who in his glory was not ashamed to acknowledge his brothers, however lowly and abject their condition. He is the great sacrificer and bishop Melchizedek, who has offered an eternal sacrifice once for all. He is the sovereign lawgiver Moses, writing his law on the tables of our hearts by his Spirit. He is the faithful captain and guide Joshua, to lead us to the Promised Land. He is the victorious and noble king David, bringing by his hand all rebellious power to subjection. He is the magnificent and triumphant king Solomon, governing his kingdom in peace and prosperity. He is the strong and powerful Samson, who by his death has overwhelmed all his enemies.”

In short, “If one were to sift thoroughly the Law and the Prophets, he would not find a single word which would not draw and bring us to him.” 

No wonder Paul can say he knows nothing but Christ and Him crucified; knowing that, you know a lot.
