We are dedicated to confirming salvation is through "putting into practice" the words of Jesus, just as Jesus teaches in his lesson about building on the rock as opposed to on sand. Paul's message is obviously different. The church knows this, and so a doctrine was developed called Dispensationalism. You maybe never have heard of it. But it teaches that Jesus, the man, was inferior to the resurrected Jesus who alone spoke from heaven to Paul. Jesus' teachings are supposedly flawed, and still affected by weakness, as Luther taught in his Preface to the NT from 1522 until he removed that statement in 1545. Luther had written -- which echoed over the centuries since: "There is no man living on Earth Who knows how to distinguish between The law and the gospel … even the man Jesus Christ was so wanting in Understanding when he was in the vineyard that an angel had to console him though he was a doctor from heaven he was strengthened by the angel.” Luther, Luther Works 54, 127.
