The Proof of Salvation: God’s Promise, Not Man’s Perseverance[Perseverance of the Saints] John 10:27–29; Romans 8:38–39; 1 John 5:13 (KJV) Salvation is not a test of human endurance, but a promise secured by God. Assurance comes not from our ability to persevere, but from the Shepherd who holds us and the unbreakable covenant of His love.I. The Shepherd Secures His Sheep – (John 10:27–29) Jesus guarantees the safety of His flock. Our security rests in His hand, not in the fluctuating strength of our own faith. God’s promise is eternal, and nothing can separate the believer from Christ.II. The Believer’s Assurance in Christ – (1 John 5:13) The Bible gives believers confidence: salvation is known and assured for those who believe. The real danger is not losing salvation, but failing to recognize and rest in the certainty of God’s promise.III. The Eternal Consequences of Rejecting Grace – (Romans 8:38–39) Nothing can separate believers from God’s love, yet rejecting His grace carries eternal consequences. Assurance is found in trusting God’s promise, not our fleeting perseverance.This sermon challenges listeners to place their faith fully in God’s unchanging promise. The proof of salvation is divine faithfulness, not human effort. The question is settled: Will you rest in God’s promise or rely on your own strength?
