Echoes of Sinai follows Rabbi Avraham Klein as he wanders his modern city day after day, carrying on a quiet, stubborn argument with the Presence that walks beside him. In alleys, markets, buses, and tenement stairwells, he meets thieves, frightened children, grieving women, worn-out workers, and bored teenagers, and in every small crossroads he hears the same question: Will you move toward them, or away? The book becomes a chain of street-corner parables where faith isn't about perfect doctrine but about what we do with the person in front of us?whether we protect, listen, intervene, or stay silent. As the days pass, the line between prayer and sidewalks blurs: the city itself becomes his Sinai, and he realizes revelation is not a thunderclap on a mountain but a continual invitation to mercy in the ordinary, echoed in every human face he dares to really see.
