How do we know God's protection is certain for believers?

The assurance of God's protection for believers is explicitly laid out in Isaiah 54:17, which states, 'No weapon that is formed against thee shall prosper.' This promise reflects God's sovereign control over all events, as He is the creator of all things, including those who would oppose His people. Throughout Scripture, we see examples of God's faithfulness towards His people in times of trial, and this promise serves to reinforce that God actively safeguards His servants against any form of spiritual or physical attack, affirming their ultimate victory in Him.
