What does the Bible say about the evidence of salvation?

In discussing salvation, Matthew 25 presents a key perspective that emphasizes gospel identity over mere actions. The righteous, who are true believers, demonstrate their salvation by their inherent connection to the gospel—they feed the hungry and clothe the naked, not as meritorious acts but as natural outflows of their faith. The evidence of salvation lies in the believer's relationship with Christ, leading them to act in accordance with His teachings. This points to the transformative work of the gospel rather than as a checklist of 'good works' that must be completed for salvation, reaffirming that grace precedes righteous living.
