During His earthly ministry He minstered exclusively to Israel: “But he answered and said, I am not sent but unto the lost sheep of the HOUSE OF ISRAEL.” His whole ministry to the Nation was under the Law of Moses. During His present ministry in Heaven, He is ministering according to what he revealed to the Apostle Paul. He is saving men according to His gospel of Grace.He is at the throne of grace making intercession fo us. this is not to say we should neglect the rest of the Bible. It is all for us but not all TO us.
