What does the Bible say about examining oneself for faith?

In 2 Corinthians 13:5, Paul urges believers to 'examine yourselves, whether you be in the faith.' This examination is not about introspection focused on our own deeds but rather about assessing our reliance on Christ and the gospel. The call is to scrutinize our understanding and assurance of what Christ has done for us, which requires looking beyond our actions to the truth of the gospel. Self-examination should provide confidence through Christ’s work as the foundation of our salvation, not a checklist of our actions.
