"自信過剰な信者は神の目には悩んでいる不信者よりも大きな罪人です。"

Simplified Meaning:

Imagine someone who is very confident that they are always right and never questions their actions. This person might make mistakes or hurt others but never thinks to reflect or change their ways. On the other hand, think about someone who often doubts themselves and worries if they are making the right choices. This person might not have strong beliefs, but they are always trying to do better and learn. In life, it's better to be the second person. Constantly questioning and striving for improvement is more valuable than blindly believing you are perfect. For example, in history, leaders who never considered they could be wrong often caused great harm. Meanwhile, those who admitted their flaws and worked to fix them were admired and respected. So, rather than being overly confident and assuming you can't make mistakes, it's wiser to stay humble and constantly seek to learn and grow. This mindset helps you develop as a person and build stronger, more positive relationships with others.
