Meanwhile, "by God" adds a touch of faith or hope in a positive outcome, suggesting the belief that fate, destiny, or a higher power will intervene and provide a favorable result despite the lack of planning or knowledge.
The phrase can be used when there is uncertainty, hesitation, or lack of knowledge, and a person is forced to make a decision or take action without proper information or guidance. It can also indicate a willingness to rely on luck or chance rather than investing effort, time, or resources into finding a more certain or effective solution.
Overall, "by guess and by God" conveys a sense of muddling through or making do with limited understanding or resources, leaving the outcome to chance or divine intervention. It implies an element of risk and uncertainty, with the hope that circumstances will ultimately favor the person or situation despite the lack of careful planning or preparation.
