Marcion, a popular but controversial early Christian leader, tackles the question of how to believe in a good God in the face of evil things happening. Plato introduced the idea, and other first- and second-century thinkers drew on the idea, of a 'demiurge' – a creator god who deals with the world. The perfect and transcendent God would never create a world of bad stuff but lovingly dispatched a savior to offer a way out of the world of suffering.
