Why should Christians have confidence in their salvation?

Confidence in salvation arises from the biblical promise that God is the author and finisher of our faith (Hebrews 12:2). According to Philippians 1:6, He who began a good work in you will complete it until the day of Jesus Christ. This assurance is not grounded in human ability but in God's faithfulness to His promises. The good shepherd's commitment to securely hold His sheep ensures that true believers will persevere in faith. The security of our salvation is anchored in Christ's atoning work and the promise that nothing can separate us from the love of God (Romans 8:38-39). This gives us an unshakeable assurance even in times of trial.
