What does it mean to die to self in Christianity?

In Christianity, dying to self encapsulates the idea of recognizing our utter helplessness and the futility of relying on our own works for salvation. The sermon illustrates this through Manoah’s realization of his worthiness of death in the presence of a holy God, echoing Isaiah's lament. It emphasizes the need for believers to understand that their good deeds cannot make them righteous before God; rather, they must trust wholly in the righteousness provided through faith in Jesus Christ. This self-denial is an essential aspect of true faith, where one acknowledges their sinfulness and the necessity of Christ's atonement to stand justified before God.
