According to Hurtado, Jesus' death was interpreted as a redemptive death "for our sins," in accordance with God's plan as contained in the Jewish scriptures. The significance lay in "the theme of divine necessity and fulfillment of the scriptures," not in the later Pauline emphasis on "Jesus' death as a sacrifice or an expiation for our sins." For the early Jewish Christians, "the idea that Messiah's death was a necessary redemptive event functioned more as an apologetic explanation for Jesus' crucifixion" "proving that Jesus' death was no surprise to God." According to Krister Stendahl, the main concern of Paul's writings on Jesus' role, and salvation by faith, is not the individual conscience of human sinners, and their doubts about being chosen by God or not, but the problem of the inclusion of gentile (Greek) Torah observers into God's covenant.
