What does the Bible teach about assurance of salvation?

Assurance of salvation is a key tenet within the Reformed faith, rooted in the security provided by Christ's sacrifice. John 10:28-29 illustrates this, stating that no one can snatch His sheep out of His hand. This assurance is given to believers through faith in Jesus Christ, not based on human merit or works but on His grace. Moreover, Romans 8:38-39 reinforces this by declaring that nothing can separate us from the love of God in Christ. Understanding and believing this truth enables Christians to live in the freedom and confidence of their salvation.
