Autor analizira moralnu situaciju Izraela prema knjigama Starog zavjeta. Ističe duboku povezanost starozavjetne moralnosti i religioznosti, sve povezano s Jahvinom objavom. Čovjek je pozvan da Bogu pozitivno odgovori posluhom vjere. Negativan odgovor Izraela Jahvi jest grijeh odnosno grješna situacija Izraela u cjelini i pojedinca u njemu. Grijeh je pobuna čovjeka protiv Boga, neposluh njegovoj volji i svetosti. Na to se, kao izlaz, nadovezuje tema kajanja i obraćenja naroda i pojedinca k Bogu. Na tome posebno inzistiraju proroci. Jahve reagira na obraćenje oproštenjem grijeha, povezano s povijesnim i eshatološkim darom spasenja., Author analyses the moral situation of Israel in the Old Testament. He analyses the fundamental topics of the OT. First of all, he stresses the morality as an element of religion, closely linked with the Revelation of Yahweh whom the man is due to answer to. The answer can be a positive or a negative one. Hence the author analyses the negative answer of Israel to Yahweh that is sin, the sinnful situation of Israel and of each one in Israel. The author analyses the concept of sin according to the OT theology showing the sin as rebellion against God, against his will, against his saintety. Further, the author is analysing the conversion of a man and of a whole Israel. The Prophets of the OT were inviting the Israel and each one in Israel to conversion, to abbandon the sinnful living and to repent their sinns. When Israel is converting (hebr. šub) to his Yahweh and is repenting his sinns, God forgives the sinns and introduce the Israel and each one in Israel to the Everlasting Life, the union with God. Hence, author analyses the biblical concept of salvation, the historical and the eschatological salvation. The paper is done respecting the modern biblical literature.
