What does the Bible say about fear and trust in God?

In Matthew 10:28, Jesus instructs His disciples to 'Fear not them which kill the body, but are not able to kill the soul: but rather fear him which is able to destroy both soul and body in hell.' This emphasizes the need for believers to place their trust in God rather than in the fears of this world. The repeated call to 'fear not' throughout Scripture reassures us of God's sovereign control over all circumstances. As seen in Isaiah 41:10, God promises His presence and support, reminding us that we are not alone in our struggles.
