Why is it important to fear God?

In Luke 12:4-5, Jesus instructs His followers not to fear those who can kill the body but rather to fear Him who has the authority to cast into hell. This healthy fear acknowledges God's sovereignty and power in matters of eternal significance. It should provoke humility and a sense of accountability before God, prompting believers to live in a manner that is pleasing to Him. Recognizing God's authority ultimately leads to comfort as we understand that while the world can threaten our physical existence, only God determines our eternal destiny.
