What assurance do believers have of their salvation?

The assurance of salvation for believers rests firmly on the character and promises of God, rather than on human effort or feelings. Romans 8:38-39 assures us that nothing can separate us from the love of God, reinforcing the idea that Christ’s intercessory work is effective for the elect. Additionally, 1 Thessalonians 5:24 states, 'Faithful is he that calleth you, who also will do it,' which emphasizes the reliability of God's promises to fulfill His work of salvation. Believers can have confidence in their eternal security, knowing that Christ's redemptive work and the Holy Spirit's sealing guarantees their perseverance until the end.
