38 Certainly Job could complain before God about the presence of incomprehensible and apparently unjustified suffering in the world. In his pain he cried out: “Oh, that I knew where I might find him, that I might come even to his seat! ... I would learn what he would answer me, and understand what he would say to me. Would he contend with me in the greatness of his power? ... Therefore I am terrified at his presence; when I consider, I am in dread of him. God has made my heart faint; the Almighty has terrified me” (23:3, 5-6, 15-16). Often we cannot understand why God refrains from intervening. Yet he does not prevent us from crying out, like Jesus on the Cross: “My God, my God, why have you forsaken me?” ( Mt 27:46). We should continue asking this question in prayerful dialogue before his face: “Lord, holy and true, how long will it be?” ( Rev 6:10). It is Saint Augustine who gives us faith's answer to our sufferings: “ Si comprehendis, non est Deus ”—”if you understand him, he is not God.” Our protest is not meant to challenge God, or to suggest that error, weakness or indifference can be found in him. For the believer, it is impossible to imagine that God is powerless or that “perhaps he is asleep” (cf. 1 Kg 18:27). Instead, our crying out is, as it was for Jesus on the Cross, the deepest and most radical way of affirming our faith in his sovereign power. Even in their bewilderment and failure to understand the world around them, Christians continue to believe in the “goodness and loving kindness of God” ( Tit 3:4). Immersed like everyone else in the dramatic complexity of historical events, they remain unshakably certain that God is our Father and loves us, even when his silence remains incomprehensible.
