Based on Bultmann’s theologicalthinking and his existentialist hermeneu-tics, the article focuses on justificationand its relationship with faith as an es-chatological event as obedience and de-cision founded on the act of the God’sgrace according to the theology of theApostle Paul. Thus, the article points outthat, consisting of the God’s justice in apossibility for the listeners of the prea-ching before the absolute character ofthe dominion exercised by the power ofsin in a process that subjugates all hu-man beings to slavery and implies theimpossibility of justification before ofGod through the works of the Law, fai-th as obedience and decision constitu-tes the eschatological event in a cons-truction that encloses it as the new sal-vific path that, emerging as the law of fai-th, opposes the law of works, convergingto justification as God’s justice. Thus, iffaith is a concession from God in a mo-vement that contains the idea of pre-destination, such characterization doesnot imply, however, an operation thatexempts the human being from the res-ponsibility of the decision-making act butconsists in the fact that the referred pos-sibility it maintains absolute dependenceon the God’s grace and, thus, constitutesan event in which the decision can onlyemerge as a gift from God.
