28 This discovery of love as a source of knowledge, which is part of the primordial experience of every man and woman, finds authoritative expression in the biblical understanding of faith. In savouring the love by which God chose them and made them a people, Israel came to understand the overall unity of the divine plan. Faith-knowledge, because it is born of God’s covenantal love, is knowledge which lights up a path in history. That is why, in the Bible, truth and fidelity go together: the true God is the God of fidelity who keeps his promises and makes possible, in time, a deeper understanding of his plan. Through the experience of the prophets, in the pain of exile and in the hope of a definitive return to the holy city, Israel came to see that this divine "truth" extended beyond the confines of its own history, to embrace the entire history of the world, beginning with creation. Faith-knowledge sheds light not only on the destiny of one particular people, but the entire history of the created world, from its origins to its consummation.
