What does the Bible say about knowing if you're saved?

In Luke 18:9-14, Jesus illustrates the difference between a lost man and a saved man through a parable about a Pharisee and a publican. The Pharisee trusted in his own righteousness while despising others, believing his good works were sufficient to justify him before God. In contrast, the publican recognized his sinfulness and pleaded for God's mercy, trusting only in the blood of Christ to save him. This parable demonstrates that salvation is not based on our actions or perceived goodness, but solely on God's grace and mercy as revealed through Christ. Therefore, knowing one is saved hinges on one's trust in Christ, not oneself.
