How does perseverance relate to salvation?

In 2 Timothy 2:11-13, Paul declares that 'if we be dead with him, we shall also live with him; if we suffer, we shall also reign with him.' This means that those who endure and remain steadfast in their faith will share in the glory of Christ. Perseverance is not merely about enduring hardships but about sustaining faith in Christ alone. It assures believers of their salvation, as genuine faith will persevere until the end, evidenced by looking solely to Christ for acceptance before God.
